tough titty

Suck it up, deal with it, and quit whining.

Quote from Little Shop of Horrors (Arguably the best musical film of its time):

"Plant: Feed me!
Seymour: No! No more! I can't take living with the guilt!
Plant: Tough titty!
Seymour: You watch your language!

Plant: Aw, cut the crap! Bring on THE MEAT!"
