someone asked for some British slang in another thread, and I think this could be broadened to slang from anywhere that's not US-National (ie to include localised slang in the US, and anywhere else globally)
to start the ball rolling, some UK ones...
Drunk - mullered, rat-arsed, pissed as a fart
Ugly woman - Swamp Donkey, minger, boiler
Fat ugly woman - bloater, sperm whale
I also include this link to a page I did waaaaay back for euphemisms for the act of love
here
so, what are yours?
