A sarcastic term originating from yuri-bait. The word would initially suggest that it's a pair of characters that give a surface impression of being
straight from their interactions with one another, but actually aren't. However because
people perceive any character in the media as
straight until proven otherwise, which is usually correct, this term is mostly just used to make fun of presumed straightness by using an analogous word to yuri-bait which is pretty common.
Those two characters seem to like one another. Are they actually gonna be
straight or is that just another het-
bait?
I bet those two characters that are together on the poster will be just another het-
bait!
