A woman who is half turtle half man. She lives her life with her neck outstretched and her face in others. She is one of the most social, extravagant, freaky turtle-ladies you will ever come across. Occasionally she will tend to target one person, and either bully them with her words or physically air hump them, whichever she is in the mood for. Either way way she is one hell of a gal!
Man 1: "Whoa man did you see Je'Leese?! She was like totally humping me on the dance floor last night!"
A girl who is not hot in any way but still tries to dance like a whore at clubs; a wannabe slut; also very clingy girl, with same characteristics
Derived from the aspect that real sluts are "loose", while a leesey is not loose, but wants to be, so she is "leese".
Guy: Dude, where have you been?
Wingman: You SO owe me man, I got stuck with another leesey!
or
Guy: *panting* Man, we gotta go!
Other Guy: What is it?
Guy: *looks over shoulder* That leesey just tried to kiss me!
Other Guy: *panicked* Oh (expletive), duck down and follow me!
