look up any word, like dirty sanchez:
A fugly loser, essentially; one who not only fails at life and in general, but one who does so in an extraordinarily ironic or awful manner.

A permutation of floser, often mistaken as a f*cking loser.
Mark: ...and so when I tried to sneak the new wireless router back into my house, I pushed the door open with my back, then turned around right into my mom...

Gus: Flooser!

A very uncommon term used by few very cool people, combination of the term 'fuck' and 'loser'.

Person 1: Hey, Person 2, look at my tower of cards!
Person 2: Um, ok, maybe I would, if you weren't a flooser.
