Gavin

Gavin is the biggest liar you know, he is always making up excuses to try to make himself feel better and put others down. Everybody knows him, but nobody likes him, he spends most his days alone in his room.

Gavin wasn't invited, but he still showed up.

Wrendan

Someone that is unlikable and nobody enjoys hanging out with, everybody hates him.

That guy is such a wrendan
