A photograph of your tits, which are used as a "stunt double" for your girlfriends because they don't want to send guys photos of their own. Used in texting mostly.

Often times the person with the stunt rack, is very proud of their tits and has no problem using them in this way.
Tami, "hey Betty, text me that photo of your tits I need to use it as a stunt rack and send it to this new guy I met online."

Betty, "Sure, you want the one in the pink bra or another one?"

This always results in the guy texting the girlfriend right back, "NICE RACK!", hence getting the girlfriend a 1st date.
