The most awesome goth guy you will ever meet, he's always there for you and goes out of his way to make sure that you have a smile on your face and warmth in your heart. The best friend you could ever wish for, don't let him go. This is one guy that you wouldn't mind being around for days at a time, and you look forward to speaking to him because he always finds a way to brighten your day.

Sarah: He must be a Greg, Gregs make the best of friends.

Dude, everything was fine and then he totally Gregged out out of nowhere.
