Usually said out of impulse, and unprovoked. The "tits" part is held on and exaggerated, and along with a gay voice it sounds very annoying. People usually say this when they are trying to make people like them.
A: you want to go to a party later?
B: yeah, sure. call me when you're ready to come get me.
(2 hours later)
A: i'm gonna come get you now
B: i fell asleep and am not feeling well
A: you're really saggy titting it this time

Saggy Tits
Do your tits hang low?
Do they waddle to the floor?
Can you tie them in a knot? Can you tie them in a bow?
Can you throw them over your shoulder.. etc. etc.
Basically boobs that are either so big that they are touching your belly button or your just REALLY old.
