i won't hold my breath

A phrase given in response to something you know is not going to happen.

In other words, you'll "die" waiting on this particular thing to happen.

Him: "I know i've hurt you alot in the past, but i promise it won't happen again"
Me: "I won't hold my breath"

no I won't make out with you

A phrase that a guy says to a girl loudly in a public place to attempt to embarrass that girl. This is usually sarcastic and said to a complete stranger who wants to ask a guy something simple.

The phrase originates from the movie "Billy Madison" when Adam Sandler's character makes an ass of himself while trying to fit in in high school...

Girl: "Excuse me, do you have a pen I could borrow?"

Guy: "No I won't make out with you!"

Don't start nothing won't be nothing

A warning to others stating that if an altercation is to be avoided than they should cease acting in a provacative manor.

late night stick that won't quit

When a guy wakes up in the middle of the night, with a huge erection. A guy will try to ignore his erection and try to go back to sleep (because when you're tired, it's hard to wank it).

The problem with this is, the more you ignore it, the harder it gets and the longer it keeps you awake. So you're only choice is to just beat it, ejaculate, and go to sleep in your orgasmic state.

I woke up at 3 in the morning last night, and had a late night stick that won't quit, and I was up 'till 4:30 until I decided to just beat it the fuck up.

I won't tell if you don't

Convenient phrase used to assure any person being approached by an interested party that they made the right decision in initially turning them down them with the "sorry, I have a boyfriend/girlfriend/significant other of non-specific gender" line. Often followed by a cheeky wink, just to really bring it home.

The war-cry of the asshole.

Guy: "hey gorgeous, do you think I could take you out some time?"
Girl: "aw that's sweet, and I'm flattered, but I have a boyfriend"
Guy: "no sweat baby, I have a wife and three kids at home. I won't tell if you don't"
Girl: "oh gosh really? Thank goodness, that was my main concern. Pick me up at 7, and bring a three-pack of Durex"

I promise I won't tell

The biggest lie anyone has ever told; everyone has used this at least once

Person 1- I can't tell you
Person 2-I promise I won't tell
Person 1- ok but you can't tell anyone
Person 2- I won't
..later on
Person 3- what did they say?
Person 2- yup he likes you

I won't go to sleep on you.

You will do what you say you will do!

Don't worry, I'll remember our agreement, "I won't go to sleep on you."
