Greg

A person who throws up after/during every party where people are getting intoxicated. Even if there isn't any alcohol around he'll find a way to vomit all over your mom's expensive Persian rug.

P1: What happened to my mom's Persian rug?

P2: Looks like Greg pulled a fast one.

P1: But it was only my sister's sixth birthday.. My dad was the only one with alcohol and all he had was a glass of wine!

P2: Greg always finds a way...
