Pull a K Rich
Say you're going to do something, then proceed to cancel whatever it is you were going to do. Usually accompanied by a lame ass excuse such as "I have a headache"
Me: So Kyle when are you gonna pick us up for the movies?
Kyle: Oh, I cant dude, I have a headache. Sorry.
Me: Wow, I can't believe you would pull a K Rich.
Kyle: Oh, I cant dude, I have a headache. Sorry.
Me: Wow, I can't believe you would pull a K Rich.
