Cojones. C-O-J-O-N-E-S. Cojones. Spanish slang meaning testicles/nuts/balls/nads/rocks. Pronounced co-HO-ness. As in, "Bush is claiming unitary executive powers? Man, them's is some cojones right there."
Your alternative is cajones, or "drawers." Like a chest of drawers. Not quite as awe-inspiring, if you think about it.
This lesson in vulgar slang has been brought to you by letter H and the number 12.
