Big Shot: Noun. An important or influential person.

Mischa Barton's rep has confirmed that the former "O.C." actress recently was approached for an upcoming role on "Gossip Girl" but turned it down. When are these network execs gonna get it? Mischa Barton is too much of a big shot for your little "television shows." She was on "The O.C." for like, three years. I think the girl's paid her dues. And anyway, I'll have you know Mischa is starring in an upcoming film about the Russian lesbian pop singers who had that one kind of popular song like six years ago. Starring. And don't forget about her Keds endorsement or forthcoming stint in rehab. So you think about that next time you ask Ms. Barton to take on a role in a television show almost exactly like the one who made her famous in the first place.
