The iconic phrase said by a Cleveland bus driver right before he gave the hardest uppercut given to a female by an old man. This can be seen in the viral video "Cleveland bus driver vs. woman" which millions have already witnessed. The victim (a very annoying and troublesome passenger) described it as "being in mortal combat (LOL). This phrase is now used to suggest that an uppercut/ass whipping is about to be delivered by the person saying said phrase.
A term that started from an Instagram post by the account “@rap” about Tony Hawk selling blood-infused skateboard where the famous rapper Lil Nas X commented “nah he tweakin.” Lil Nas X was annoyed that Tony Hawk wasn’t slandered for using blood in a product while the rapper was, in his custom shoes. The term spread like wildfire across Instagram.
