Which fighters are really "about that life?"

After watching Colby and Usman do whatever it is they did.... I don't know what to call it. An angry modeling contest? Well, after watching them, someone pointed out that Masvidal is about that life. He proved it.

Got me thinking. Who else is really about that life? Which fighters will actually fight out of the ring at a moment's notice?

So far I can only think of Masvidal, and Jones/Cormier.

Any others?
