Coined by Adam Carolla of Loveline. Combination of "spaz" and "loser". Spaz as in the geek who owns his own comic book store and Loser as in someone who waits outside a studio for an hour and a half for Tia Carrere to sign a copy of Playboy so he can sell it on eBay for $26.
That guy is such a sploser.
