An expression meaning to Eat Face, used by politicians, especially Republicans.
Also can be used as a Catch Phrase for Lisa Simpson of "The Simpsons" who is currently the only one on there without one.
But mostly it's a friendly greeting implying to do something digusting.
Hello, sir. How are you. I'm pretty good. How the kids? Good, huh. Oh yeah! I almost forgot to tell you. I LIKE TO EAT FACE!
