look up any word, like sex:
Fetish wherein the object of one's desire wears a red backpack, specifically a randoseru. This fetish is frequently associated with lolicon, as the randoseru is typically worn by elementary school students.
Gosh those pedobears sure do come up with some wacky fetishes. Have you even heard of red backpack? Me neither.
