Words we do not use

Refused (11)

boat equals runabout

Evidence points the other way. Boat means the machine generically not runabout specifically The evidence points the other way: riders say boat for the machine generically, not for a runabout specifically. Not a term, a misreading.

coffin

No PWC-specific source found No personal watercraft source found for it as a trick name.

cyclone

Offered as the name of a freestyle trick. No personal watercraft referent found. A project file attributes the trick to a named rider, which is an attribution and not a sighting; nobody is named here.

helicopter

Offered as the name of a freestyle spin; equated by one rider to the flat spin. Its one sighting is a single X-H2O rider in 2021 equating it to the flat spin, and no rider defines it in their own words, which is why the research note of 2026-09-21 kept it off the glossary. A later sighting would bring it back. Last checked 2026-10-07.

no-hander

Not sourced as a named PWC trick. One-handed variations as a category is sourced One-handed variations are sourced as a category of trick; this name for a no-handed one is not.

OP RUNABOUT SC/NA

JJSBA class code Carried as a JJSBA class code until 2026-10-04, on an encyclopedia page the research then read and recorded as not supporting the row. Nothing held names OP RUNABOUT SC/NA, checked again on 2026-10-05. It is refused as unsourced rather than as unreal, and a document naming it would put it back. Last checked 2026-10-04.

pop

Could not verify as PWC vocabulary distinct from general action-sports usage Could not be shown to mean anything in personal watercraft use that it does not mean in action sports generally.

purple pipe

Zero results in a PWC context. Only real referent is reclaimed-water plumbing No sighting in a personal watercraft context. The only referent found is reclaimed-water plumbing.

rodeo

Offered as a trick name on a compiled freestyle list. The word is known only from a third-party trick list of 2010 that a forum member pasted into an X-H2O thread, with no rider describing the trick, as the research note recorded on 2026-09-21. It returns to the glossary if another sighting turns up. Last checked 2026-10-07.

sinus soaker

Zero results across all searches including bare-quoted. Almost certainly not a real PWC term No sighting in a personal watercraft context by any search, exact phrase included. Almost certainly not a real term of the sport.

SKI-X

JJSBA class code Carried as a JJSBA class code until 2026-10-04, on a Japanese encyclopedia page that prints no class codes. Nothing held names SKI-X, checked again on 2026-10-05, and nothing better was reachable, so the glossary could not say what it means and has stopped implying it knows. It is refused as unsourced rather than as unreal: a JJSBA code of this form may well exist, and a document naming it would put it back. Last checked 2026-10-04.

Refused once, now in the glossary (7)

Words the first pass refused and a later pass found. Each is now in the glossary in its family, at the grade its sighting earns, and keeps the note of what cleared it.

nose stab jargon, likely

A named freestyle trick. Refused on the first pass as a wakeboarding and snowboarding word; then sighted as a named freestyle trick on two forums, in 2016 and 2021, with a definition in a rider's own words that is not quoted here. Cleared 2026-10-07.

pit party jargon, likely

A gathering in the pits on a race weekend. An established supercross term; cleared for the sport from posts about Northeast race weekends in 2013, so regional until sighted elsewhere. Cleared 2026-10-07.

re-boarding jargon, likely

Getting back onto the craft from the water. First read as manufacturer safety-course language; then found in riders' own use, mostly as one word, reboarding. Cleared 2026-09-21.

run whatcha brung jargon, confirmed

An open class or event where riders race whatever personal watercraft they bring. IHRA's drag rules call the Unlimited Class basically a run what you brung class, open to any PWC but barring surface props, and print Run What Ya Brung for the Stand Up Unlimited and 2 Stroke Unlimited classes. Sighted from three forum posters between 2006 and 2008, none of whom spelled it whatcha; IJSBA's own page is quoted elsewhere as run watcha brung. Cleared 2026-10-07.

spin out jargon, confirmed

The two-word form of Spinout, which the IHRA rulebook glossary defines; also used by riders for losing the tail in a turn. The IJSBA general rules head GEN.10.5 Spin Outs, which lets a rider whose boat has spun out turn around once the course is clear. Refused on the first pass, then found defined in the IHRA rulebook glossary as Spinout and sighted on three forums in two senses. Cleared 2026-10-07.

submarining jargon, confirmed

Burying the bow under the water, as a riding term. PWC Offshore's 2008 Catalina ride page describes it as the nose going under the water, usually after the craft gets air and comes down nose first into the next wave. Cleared as a riding term for burying the bow; a race-specific use is still unshown. The freestyle trick called the submarine is a different thing. Cleared 2026-10-07.

Superman jargon, contested

A named freestyle trick, listed in riders' trick lists without a description of the move. First found only in a stock-photo caption; a second sighting in 2013 credits the trick to a rider, who is not named here. A separate sit-down speed-run posture sense exists and must not be merged with it. Cleared 2026-10-07.

Refused once, real, and still not a word of the sport (2)

Strings the first pass refused that turned out to be real, and to be something other than vocabulary: product names, which belong in the parts catalogue.

Coffman Classic

A Coffman pipe name, seen in sale listings over several years and absent from the manufacturer's archived site Refused because it appears nowhere in the Coffman archive; then found as a real, repeatedly sold Coffman pipe name in sale listings across several years. A product name, not a word of the sport: it belongs in the parts catalogue, not here. Cleared 2026-09-30.

Coffman Climax

A Coffman pipe name, seen in sale listings over several years and absent from the manufacturer's archived site As for Coffman Classic. Cleared 2026-09-30.
