A somewhat derogatory name for the computer game Ultima 8, said so in large part because in comparison with the previous games emphasis on character interaction and plot, this game featured many "puzzles" in which the avatar (your character) had to jump from platform to platform, with an automatic death sentance for missing a jump, reminiscent of the older nintendo Mario games.
Ultima Dragon 1 : Damn, I expected better from that game.
Ultima Dragon 2 : Which Ultima was it?
Ultima Dragon 1 : Super Avatar Bros
Ultima Dragon 2 : Well, it's at least way better than Ultima 9, that gawdawful piece of shit

A slang name for the Origin computer game Ultima 8, due to the large (in some opinions excessive) amounts of jumping required to complete the quests.

Nerdy guy "Dude, I just beat Super Avatar Bros.!"

Other Nerdy guy. "Fagbag, the series started to suck after seven and you know it."
