A word made famous by professional wrestler Bobby Lashley. He meant to say "bastard," but he speaks with a lisp, and instead it came out like "bathturd." It instantly became an internet phenomenon incredibly popular within the Internet wrestling community. It made Lashley full of teh lulz.
"You say your name is Finlay, and you love to fight...well I say your name is Finlay, and you're a bathturd."
