the act of video recording on the snap chat application to a song without one's own voice but by a pre recorded track. This is usually done in a moving vehicle or on ones couch at home.
I really enjoyed the snap chat lip sync I received from my friend Eli. It really made my day.

Get the snap chat lip sync mug.
A sexual maneuver involving the mouth, your girl's ass and bowel movements.

You have your girl laid flat on her back your face is flat on her naked ass. The girl then proceeds to defecate. You hum to any song very loudly whilst having your mouth open and you chew on the poop that comes out of her ass. It's similar to an easier masturbation, but jacking off to someone is replaced by humming to someone's song and you're dipping your mouth into your girl's poop instead of ejaculating.
I really liked PewDiePie's new diss track. So i got my girlfriend with me and i did a scandinavian lip Sync to congratulations. But my tongue is very brown now and my face is covered with poop.
