"Call me once, you're done" SONG HELP?

On October 24th in an AE, I heard a song with a catchy beat and a male singer. The first line was something along the lines of "call me once, you're done. Classic move."

Help? :]

"do it or diet" - the big big bucks

does anyone know where i could find this?! i've looked all over the internet and itunes.
