na beh
A super rude way to say 'fuck your mom' or 'fuck your mom's stinky hole.' It’s like throwing a punch in a crowd and hoping no one notices it was you.
My cousin said 'na beh' to my uncle after he took the last slice of cake.
She texted me 'na beh' because I forgot her birthday and her cat died.
He yelled 'na beh' at the bus driver for making him miss his favorite show.
