Similar to the phrase "Blowing smoke up my ass" but telling a person a lie to avoid telling the truth. This is especially done when caught in the wrong or other compromising positions.
"Jim caught his wife with another man at McDonalds; they were holding hands and everything!"
"Really, what happened?"
"Well she started trying to say the guy was just a friend"
"Seriously?"
"yep, I heard Jim kicked her ass to the curb, now she's staying with her 'friend' at his place."
"Man doesn't that beat all."
"Yes sir. I don't know how he's handling it so well... I would kill my wife if she was cheating on me, and then tried Blowing Air Up My Ass."
