The practice of alternately dedicating the 6 urinals in the toilet boy girl boy girl boy girl. Using a "girls" urinal was tantamount to a confession of homosexuality and it wasn't uncommon to see boys desperately hopping from foot to foot waiting for a boys urinal to become free. Anyone unaware of the rules who blithely used a "girls" urinal would rightly be greated with screams and howls of disgust. I think the stupidity of this was apparent to us even at the time, that said the looks of confusion at being admonished for using a "girls" urinal are quite unlike anything I've seen since. The game recieved a welcome revival in 4th year at secondary school when a new toilet was built which had individual urinals instead of the "trough" style which had to be declared single gender as a matter of logistics. The fun was partially sucked out of the game when upon shouting at a first year that he was gay for using a "girls" urinal he told us to "grow up and stop being a bunch of tits".
