Bel, you had the post about the difference between pissed on and pissed off-- but do you know why piss is yellow and "cum" is white?
So a drunk (or substitute ethic group of choice) will know whether he is coming or going...

and curiously-- in Japanese-- one uses Going as the term for an organism, and coming as the term for uninations-- proving that in japan a western doesn't understand anything and never knows whether he is coming or going!

and in french--my meager french allows me to count to 5, and say "in the name of the Father, the son,and the Holy Ghost, Amen-- Hail Mary... i mangle the days of the week, and months of year.... and certainly don't know any street slang--So do french men come-- or go (or rather in which room do they come or go!) Or would you rather not say?
