Quippoorwill 

Much like the whippoorwill bird with its incessant call, the quippoorwill is a person who cannot stop quipping; one who endlessly quips, on Facebook and in person.

Neal: All this talk about the economy has got me depressed. I'm gonna go spend my last ten bucks on a six-pack of non-alcoholic beer and get 0.5% drunk.
Bob: No, don't do it!
Neal: I could probably pick it up at Whole Foods. Do you think they'll let me in without my North Face windbreaker and overbrewed coffee?
Bob: Dude, you're like a quippoorwill, or something...
Neal: I got more quips than Picasso got paint.
