Floppy Twat 

A bastard or cunt who is stingy and doesn't help you when you need it.

Jake: Hey man, can I borrow one of your condoms for my hot date tonight?
Floppy Twat: No man, I don't have enough left.
(Floppy Twat knows he isn't going to use them, but makes Jake suffer anyway)
Jake: You floppy twat.
