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.

boob-over 

boob-over; Semilar to the "comb-over" as with a loss of one boob a female will wear a tube top and slosh a purtion of the remaining tit sidesways so as to give the impression there is a full pair hiding under her blouse.

Tony; Yeah, so like, I thought I was gunn'a get lucky with Amilia and when I reached into her tubetop for a little feel...like shit man, out pops this one big saggy tit.

Lee; What, are you kidding? So what happened to the other one, a tit-ectemy?

Tony; Donn'o dude. It was the wierdes't thing ever. Like a boob comb-over.

Lee; That's so sick! Chicks with one tit should just face being bald chested instead of doing that gross boob-over thing. Eueeeww!

boob-over 

a professor of law with an extensive comb-over who is a poor teacher, goes off on tangents and is excruciatingly boring.

What the fuck is this boob-over talking about? I just fell asleep for forty minutes.

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!

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.

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.
