breathing air 

when a person doesn't know what they are talking about or making stupid statements.

Don't pay no attention to him he's just breathing air. Don't listen to anything she says, she's just breathing air.

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."

beating air 

When you’re masturbating, but you’re just not into it

I was beating air all night, I just couldn’t get off
