overboob 

when one's bra is too small, and one or both boobs are poking over the top of the cup. there are varying degrees of overboob; and when a severe case affects both boobs, it is called quadriboob.

I haven't worn this bra in a while, I must've outgrown it... I've had overboob all day long and no one told me!

Overboob 

Much like the "sideboob" the "Overboob" is the part of a woman's breast that is exposed or casually visible by others.

I think she needs a bigger bra. Look at all that "overboob" hangin' out.

Over Boob Cleavage 

The gap between a tight fitting shirt and a woman's breasts seen from the side. This is the most sexual type of cleavage and should never be overlooked.

Boy 1: Yo dude, see that chick over there?

Boy 2: The masculasian?

Boy 1: No way man, the other one.

Boy 2: The one with the sexy gap between her boobs

and shirt?

Boy 1: Basically, that's Over Boob Cleavage.

Boy 2: Shit son! That's the sexiest thing ever.

Overboobage 

Of women, when one's (bra) cup runneth over slightly, marring slightly the smooth convex curve of bra and boob-top. A tiny amount of overboobage is intriguing, but excessive overboobage leads to the much-feared four-boob effect. Overboobage is most prevalent in push-up bras, but can be found in any over-tight bra that is not full-coverage.

Bring me another bra. This one's cups are too small, and I'm getting severe overboobage.

Overbomb

1. Nickname of Toronto Blue Jays' first baseman, Lyle Overbay.

2. A huge jack hit by Lyle Overbay.

As Lyle Overbay is stiding up to the plate, with his at-bat music 'Jeremy' by Pearl Jam in the background, one would shout "Overboooooooooooomb!", repeatedly. And then, of course, Lyle would hit a huge overbomb.
