duderus

pronounced DOOD-erus. Synonym for a gay man's asshole. Much the same as man-pussy, butt-cunt, mangina, boygina, etc.

Because of all the fucking last night, my duderus sure was raw this morning.

Duterus

Opposite of your weenis (skin on elbow), inside of your arm where it bends. A weenis (weenus) and Duterus are one happy couple! Considered the feminine part of arm in comparison to the elbow

You just put your finger in my duterus!
