Oh no she better don’t

Another way to say “she really didn’t just go there” or “she better stop”. This line is normally said by a person on the sidelines of a conversation two people are having, like an instigator.

This line is also used repeatedly in Rupaul’s drag race

The “better” in the sentence is also pronounced “betta”

Person: “that why you built like tree bark”

Instigator: “oh no she better don’t”
