when you are so flabbergasted by a comment you have to flabbergast them back by saying “mub”
“IMAGINEEEE”
“mub”
*gasp*
To mub is to see the truth. Someone says something but you mub and realize what they actually mean. There's also an entirely different meaning for mubbing. If someone is not mubbing, they are not smart, clever, or cool.
"The teacher hasn't graded the papers yet. She says she's having family matters. The mub: she's too lazy."
"I think she likes me" "Bruh you are not mubbing."
