Don Juannabe 

Refers to one of the increasingly large group of males who assume that, like the famous Don Juan, they can seduce any woman, anytime, regardless of the fact that most women avoid them like the plague after the first 5 minutes of talking.

Also spelled "Don Wannabe" for those without the Latin flavour.

Guy: Man I hate Bob, he's such a Don Juannabe.
Other guy: Yeah, he's always hitting on my girlfriend, what a douche/moron/maroon.

Don't Pull a Kevin 

To warn someone not to write an amount such that the world graphite reserve is lessened by at least 0.72% and moving it all onto sheets of paper. Also to warn against one causing all the alphanumerical keys of at least 14 keyboards to fall off. Pulling a Kevin is strongly censured by environmentalist organizations claiming that this act causes mass deforestation.

The 14276 page essay was given zero credit, with a comment of merely "Don't Pull a Kevin".

Don’t ask questions you don’t want the answers to 

It’s usually the answer you don’t want to know.

Another form of Tom Krause’s quote
“never ask questions you don’t want to know the answers to” but more suited for using in conversation.

Often used by cheating girlfriends and wives after hoeing around.

Mark: Hey babe, where were you last night?
Susan: Don’t ask questions you don’t want the answers to

Mark: Sucked off your ex, didn’t you?

don't hold your breath 

When people hold their breaths, it's mean they're expecting something happen. So this means as an advice that "don't expect, it will not happen"

You can’t touch me now there’s no feeling left
If you think I’m coming back don’t hold your breath
What you did to me boy I can’t forget
If you think I’m coming back don’t hold your breath
(Lyric Don't Hold Your Breath - Nicole Scherzinger)
