Calls made unintentionally by sitting on a phone.
Ben Dover: I just sent my mom 2 booty calls and a text
Hairy Ballzonya: Eww dude!
Ben Dover: No not that kind of booty call
A take on the common phrase "Duty calls".
This phrase is to be said when one is about to bail on their current activity with present company because they have received a "Call of booty".
Caitlin where are you going we just got into the club?
