Corner Dog

Dude obsessed with a girl she isn't into (friend zone) who she lets sit in the corner while she's banging other dudes because she feels sorry for him and doesn't want to hurt his feelings.

I don't know what's up with Rhonda, but when I was up on that last night, every time I turned around that corner dog Peter looked me straight in the eyes and licked his lips.

Uco

An undercover police officer.

Old boy Mike had a uco living with him for months before ever getting pinched. Even hung out like we do.
