In the distance, a car screeches to a stop, making a loud, unpleasant noise. Andrea whispers to her friend about a girl she doesn't like, "That's how Tina sounds when she sings!"
Random boy says, "Dannnng, Andrea, why you gotta rip her like that?"
To fart. Academics believe that the expression comes from when you fart so hard and so loudly that you feel like you have just ripped/teared you ass. However, you don't necessarily need to rip your ass to "let it rip".
