hotline blinging

Putting your thumb on a girl's clit and your pinky in the girl's asshole so your hand looks like a phone and then shaking your had vigorously in a "surfs up dude" style

"Dude! I took this girl home last night and for a while we were just making out and then we started hotline blinging"

"I was hotline blinging this chick last night and she squirted all over my Gucci sweater."
