An American or Irish, you can't really tell, guy who punches people for a living, and he fucking punches them well.

Has the fanciest mustache the world has ever seen, and it is believed that that mustache has magical Irish powers as it stays in place even after 3 rounds of ruthless MMA.

Currently he fights in Japan because he loves sushi so much that he just had to go there.
Luke: Have you seen UFC last night?
John: Yes, Ian McCall kicked ass!

When used to refer to the mustache:
Peter: I'm thinking about growing an Ian McCall
Trevor: Don't, no one can manage to grow such a magical thing.
