Got another one: Cex. When I were a young kid in one of my old schools in maidstone kent, I used to write the word Cex. Now I obviously misspelt sex. Cex. Used to write it everywhere or engrave it on benches. Then teacher caught me and got an earful of blah.
Spearing the bearded clam or Prodding the monkeys chin as in "how did it go, did you prod the monkeys chin"? or "did you spear the bearded clam"? from Viz Profanisaurus
