Betch

[S]he'll invoke a demonic rage, siccing a gang of fiery hula hoopers on anyone who attempts to curb her obsession with footwear, and call you a "betch."

Kelly was a horribly misunderstood, very tall teenage girl who took style cues from Avril Lavigne and said things like "betch" and "shetbag."

We are told that the betch admires the Elle Woods character in the film Legally Blonde.

Betch is foremost an insult, but it is also used self-referentially as an affectionate term among fellow betches.
