OMGWTFBBQTNSA is a 1337-based (leet-based, leet is the geek way of typing "elite") sentence, meaning "Oh my god, what the fuck, barbeque, this name sucks ass". It originates from the 'word' OMGWTFBBQ, meaning "Oh my god, what the fuck, barbeque", and then someone has just put a "This name sucks ass", or "TNSA" on.
