keep your hands to yourself 

When alone in a room, it is a phrase a woman says to a pervert when she's being groped when she only wants to see you masturbate. When around other people, it's a cry of rape.

Fundo grabbed Flenda's booby. Flenda screamed at Fundo, "Keep your hands to yourself!!!" Fundo proceeded to yank it in front of her.

to make a fool of yourself 

the blatantly obvious result of incompetent damage control after you have been proven wrong in an intellectual argument

if you are decent human with self dignity do not even try to make a fool of yourself; do not attempt any form of damage control in an intellectual argument after you have been proven wrong. just accept the fact that you are indeed wrong and move on with your life.

don't flatter yourself 

a very annoying catch phrase, normally said by immature freshmen, that is used to down-play the fact that the speaker of the phrase isn't as good at something as they claim they are.

It is also used to annoy the crap out of everyone around them because the speaker could not think of something more intelligent to say.

Suraj: Did you just farticulate?
Mark: oh don't flatter yourself
