Galaxy Ripple
When you put your tongue up someone's bumhole and they let one rip so bad your tongue goes wiggly. If it's a shart, you get chocolate like it's a reward.
I did a Galaxy Ripple and got a shart. My friend gave me a chocolate bar and said I was lucky.
I stuck my tongue in my teacher’s bumhole and she let out a fart that made the whole class laugh.
At the mall, I did a Galaxy Ripple and my friend got a shart. We both ate chocolate and laughed like fools.
