crotch neck 

An ill-defined region of the male pudendum which serves as a transit depot -- or toll plaza if you will -- for all manner of venereal diseases. When stimulated the crotch neck vibrates violently, changes hue, and develops mucusy lesions. Do not socially interface with anyone you suspect may possess a crotch neck.

His crotch neck gleamed, glistened even in the light of the crescent moon, yet stank of unknown quantities of putrid anal discharge.

Melvin Crotchnick 

A half man half woman who has lots of freckles and was invented by the wonderful geniuses, Sami and Alison. It pretty much means, a nerd.

Hah, look at that Melvin Crotchnick. I bet he has no friends at school.

"Eww, get away from me, you Melvin!"
