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."
Retards who obsess over cheap, crappy e-tailer bath products and artificial smelling candles on message boards like makeupalley.com. They're usually obese frumps who want to smell like cinnamon buns, coconut fudge, chocolate frosting and cream cakes. These hags can be found with their fat asses glued to the internet 24/7 discussing soaps, wax tarts, perfume and greasy bath bombs. How many crap soaps can one person use in a lifetime?
Ah geez, if I hear about frizzy's cheap, dog-fart scented tarts one more time from those Bathtards I'm going to scream.
Short-hand for the word floccinaucinihilipilification, meaning the estimation of something as valueless (encountered mainly as an example of one of the longest words in the English language).
