Drunk Tits
When a girl is so drunk that she stumbles around with her exposed boobs flopping around.
I know she had a good time at the party because she had drunk tits.
Tit-drunk
When a man dated women solely because of their chest size, ignoring all other characteristics.
"What a rack his new bird has...but a face and body like a car accident. Yeah, he must be tit-drunk."
