jug flasher
A female (or tubby male) who enjoys flashing his/her large breasts, or jugs, either for the sexual, whorish thrill, fame and attention, or for another reason. These females are usually frowned upon by most societies in general, but occasionally will fit into groups of swingers/frats to feel included for the small price of flashing her jugs very often.
"Hey, did you hear about that girl, Brittany?"

"Yeah, I heard she flashed her shirt up to Johny so he would buy her a drink. What a Jug Flasher!"

"Yeah, she is..Let's go offer her a drink"

"Sounds good!"
