Super Boobwiggle Man

From Digibutterwiki

Super Boobwiggle Man is an avatar fad invented by Hario one day when he changed his avatar to an animated gif of Super Macho Man from Mike Tyson's Punch-Out!! endlessly wiggling his pecs. People called it "epic" and "awesome", and the avatar itself spawned a few edits, such as SBM with Sprout'd nipples, and SBM with Francis Smily nipples.
