Get the Bosh mug.
Bosh (noun) - A person who is overrated because of the people he/she either works with or hangs out with. This term was coined after the NBA player Chris Bosh, who is often overrated because he's a member of the "Big 3" with LeBron James and Dwyane Wade.
Example one:

Trent - You know I really like Michael and Gary, but I don't understand why they hang out with Dennis. He's so annoying.

Steve - Yea, Dennis gets a free pass a lot of times because he's good friends with Michael and Gary. He's definitely the Bosh of that trio.

Example two:

Richard - You know, that sales team performs really well. I think Tony, Brandon, and Alan work great together.

Nick - Actually, it's more like Tony and Brandon carry the team and Alan is just there. Their team is doing alright, but it's not because of Alan. He's the Bosh of that team.
