Essentially the effect given to the inside of the toilet bowl right after getting the beer-shits, thus resembling the outside facade of certain british pre 1970's council homes, where small stone pieces are spread over the outside wall giving a textured effect.
Tarquin: 'I wouldnt go into the bog for a good half an hour mate'

A game in which Geoff must run quickly and gather small, smooth stones. Having collected several hundred he then thrusts them up the arse of his long-suffering partner... the Tonibitch. Toni then bends over, and having eaten a Madras the night before, lets rip the foul delight of shit-stained stones onto Geoff's erect cock
Geoff: "Bend over you rotten cunt, I'm pebbledashing"
Toni: "Must we? I'm really tired of all this shit, can't we just make normal love"
Geoff: "Jesus... you fucking freak!"
Toni: <sigh>
When you have to pee in a movie but don’t want to miss anything, and must do the following mental equation: will the amount I have to pee cause enough discomfort to diminish my attention capacity for the remainder of the movie to an extent which is greater than the amount of the movie I would miss by making a mad dash to the restroom.
I saw Satantango last night, wonderful film but by the 5th hour I had to start doing pee calculus.
