Bad. Originated from a post on the keentoons forum.
"Looks like someone's a flamtastically flaming flamer."
Somebody who is just so fantastic or awesome that you cannot describe it using a normal adjective, so you use this one. Their coolness is unbound and machismo over the charts. You know that no matter what, they’ll be right by your side.
“Dude, did you actually show up for the gaming session?”
“Of course I would, dude.”
“You’re so Flamtastic.”
