And I Claim My 5

Oh dear, this is going to be complicated. This acronym is always used in the context "You are x AICM5 y" where y is in someway related to x. It is used to indicate that the person you are replying to exhibited some characteristics of person x, where person x is [a celebrity / a ukrm regular / something else]. An example might be if somebody posted a rant that was reminiscent of Bear then a response to it could be "You are Bear AICM5 lethally alcoholic drinks".

Big Girl's Blouse

A similar term to PFF, more commonly used to describe someone who's been soft on a particular occasion, rather than on an on-going basis.

A general term used to indicate to another poster that you would like the opportunity to rider their motorcycle. Abbreviated not because of it's frequent use, but more as an effort to make you look less like a scrounging git. [Footnote : Should you get a positive response to a CIHAGM? request you are legally bound, by the ukrm bye-laws, to thrash said bike within an inch of it's life. Using somebody else's bike and returning it with tread still on the tyres, con-rods still in the engine and bodywork still attach to the frame is a _huge_ social faux pas]

Often suffixed to a warning about not doing something stupid (such as painting "All coppers are bastards" on the back of your leathers) and generally taken to indicate that the poster did once try what you are suggesting themselves. Ask for the full story at your own peril.

Evil Kontractor Skum

Not strictly a motorcyling term, this refers to those amongst us who choose to whore out their talents to the highest bidder, rather than take the honest approach of getting a permanent job.

This is a reference to the "master of wit and repartee" joke, which can be found in many places on the net, including here.

Keeper Of The List

Someone who volunteers, or is nominated, to keep track of a particular acronym list. Only the KOTL is allowed to give out new numbers for their list.

Points Finger, Clicks Tongue & Winks

Apparently, using this version of the acronym is lame, as in the real version, the "Wink" is implied by a semicolon. Or something.

Points Finger Clicks Tongue and Winks

One for the unreconstructed 70s throw-backs, and self-obsessed Soho trendies. Originally the trademark of Tom O'Connor. Apparently there's no "w" in this "true" version of the acronym as the semicolon is supposed to look like a wink. I blame too much IRC-usage.

Pansy Foo-Foo

Not a particularly hard person; a bit soft; not one given to riding in the rain/cold/snow/wind/slight amount of cloud in the sky. Compare with RTB.

Rufty Tufty Biker

Pretty much the opposite of PFF - a "real" biker; the sort that rides to work for 75 miles in the snow with only a t-shirt on under their leathers.

Two Wheels Airborne

What happens shortly after you hit a bump in the road at high speed. A TWA may be intentional or unintentional and may well be your doorway into your own private world of pain (especially if this is the first time you've had to land a high speed bike or, for gentlemen, if you happen to be sitting too close to the petrol tank).

You Fat Cunt

A fairly self-explanatory term used to describe pretty much all the male regular posters to uk.r.m. except Alien Kev.

You Fucking Lightweight

Someone for whom drinking a really stupidly large quantity of beer is a bit of a problem.

You Geriatric Haridan

Only really used by one particular regular poster to describe another. Now, sadly, deprecated.

You Thick Cunt

A very widely used term on uk.rec.motorcycles; both as a genuine insult, and in a sort of friendly, laddish way. Also in the .sig acronym list.
