> As in tipping service? The same. For whatever reason false etymologies based on acronyms abound, with "tip" and "posh" being among the better-known. There's also "for unlawful carnal knowledge" for fuck, "gentlemen only ladies forbidden" for golf, "constable on patrol" for cop, etc. I've even heard people claim rap derives from "rhythm and poetry". But basically they're all bunk, apart from words of quite recent coinage. (I might add that tons of false etymologies without acronyms float around as well - "mind your Ps and Qs" being related to pints and quarts, stuff like that. Morris used to blame tour guides as being the worst culprits of keeping such things alive.)
