stop breathing my air 

Stop breathing my air is something you say to someone who is a complete waste of space. It is most commonly used when someone has said or done something unbelievably stupid.

Example:

"Yo, did you hear about that Hitler guy? Someone needs to stop him!"

(awkward silence)

"Stop breathing my air."
