Nickname for Grey's Anatomy character Mark Sloan. Dr. Sloan is played by none other than Eric Dane.

His character first broke up a marriage between Derek and Addison with a one-night-stand with Addison, which turned out to actually be a month long affair. He still has a thing for Addison, and Derek barely speaks to him. Oh yeah, and he hooked up with Callie!
