Method of choosing the 'it' for games such as 'British Bulldog' and '49 save all'. Someone (usually a bossy girl) would start pointing at people on each syllable of 'ip dip dog shit, you are not it'. The chosen one, relieved, would leave the circle. With only eight syllables, it shouldn't have been too hard to fix, but to my knowledge no-one was that clever at that age.

Ip, dip, dog shit,
Fucking bastard, little git,
You are not it
Obviously the second line serves no purpose, apart from sounding very adult.

Stand in a line? Rubbish? Everyone playing in the game put one of their feet in the dip and the bossiest kid got to do whatever rhyme they knew. On special occasions, you were allowed to put both feet in. This made it exactly twice as much fun.

Our song went:
Emilia Mason chundered in the basin,
What colour was her puke?
The person you landed on would say a colour, such as red. You would spell out R-E-D, and the person who got the D was out and therefore not it. Emilia was a girl in my class who as far as I know never actually puked in a basin, but we didn't let that get in the way of a satisfying rhyme.

Using whatever set up rhyme you liked (we had a particular favourite involving Mickey Mouse's bum) the nominated person would choose a colour for example red. The chant would then continue "R-E-D spells red and red you must have on" the person it finshed on would then have to be wearing something red or still be in for the next round. This may explain the range of disgusting colours on disply in my primary school. A good way to see girls underwear is to choose Pink. All girls wear pink underwear. The true master wore rainbow coloured pants.

Our foul mouthedl primary school version went

Ip dip dog shit

suck a fanny suck a tit

that means you are it

I remember most kids said, "It, dit, dog, shit."
Dit and shit rhymed, whereas dip and shit didn't.
