The act of stuffing a phone (on vibrate) in to a male's anus. The other partner then calls said phone while giving head to the male. If truly commited, the female will most likely lick the remaining fecal matter off of the phone upon completion.

"Wait, she didn't lick it off afterwards?"

"Dude, she might not be as in to you as you think..."
