Down Low Lurker
A man on the DL who lurks around public restrooms, parks, truck stops, porn stores, the locker room and shower at the gym, etc. looking for some random stranger(s) to have sex with.

I hate going to the gym on Thursdays after work.  There’s this creepy DL Lurker who always seems to be hanging around in the shower or wandering the locker room in a towel.

I swear to God, her boyfriend is a down low lurker.  I see him hanging around by the library bathroom three nights a week.
