A partially visible penis extruding from the waistline of a mans pants. Just like the female equivalent, this can be accidental or on purpose. The most popular sighting of dick cleavage usually involves somebody wearing their pants too low, to the point where you can see the beginning of the person in questions shaft. The less noticed sighting usually occurs when a male achieves an erection and flips it up into his waistband, causing the head of his penis to become dick cleavage.
1. "So on the bus yesterday, when Josh reached up to grab the loop to hold on, his shirt pulled up and everyone saw his dick cleavage."

2. Nobody ever wants to go swimming with Jonah, because he always wears his trunks too low, and we are all tired of looking at his dick cleavage.

That time of the year after winter. Girls stop wearing heavy coats and start showing cleavage. But if its too cold and their nipples pop out, they go back under for another 6 weeks.
Tom: "Enjoying the view, friend?"
Tyler: "Oh yes, yes indeed. Im so excited its the beginning of cleavage season, I hope Sarah's nipples don't get hard."
Tom: "Yeah, it would suck to have to wait 6 weeks to see her flaunt her cleavage again."
Jordan: "I LOVE CLEAVAGE SEASON!!!"

A game where you attempt to throw an object into a woman's cleavage.

If the woman is playing as well, the goal is to for her catch the object being thrown between her breasts. If the woman is not playing along, the goal is for the person throwing to make the object being thrown land in the woman's cleavage.

Despite common belief, it is usually played between women.
I was wearing a v-neck at lunch, and Amy didn't want her carrots, so we played Cleavage Catch.

A tasteful amount of cleavage for special times, like when you're in church or having dinner with family. No one wants to see a massive erection on the Priest or Uncle Bob.
Your girlfriend Amanda has a great rack, are you nervous about her meeting your family and your little brother staring at her boobs the whole time. Nah, it's cool, she's keeping it PG and showing only church cleavage.

Often seen in in play by female receptionists when a man arrives at the desk and towers above her for no apparent reason.

She deftly places the palm of her hand on her chin and her elbow on the desk neatly blocking all attempts to 'View the Valley' with the strategicaly placed forearm.

It is a position that can be strongly defended for hours especially when used in conjunction with a swivel chair.

Not to be confused with:
The Cleavage Offence.
Guy 1: "Aww, Maaan! Have you seen the new girl on reception? The most amazing frontage you ever man!!"
Guy 2: "Jeez! No dude. She totally flawed me with The Cleavage Defence."
Guy 1: "Yeah, she's a professional man."
