When you see someone that you're acquainted with, and they try to be abit 2 friendly and u ignore them; then they get hurt and they come around and act all brand new towards you.
" lmao I don't understand why he is trying to act brand new? He pretends he doesn't even know you're name like geez!" Haha
brand new sentence is what you say when someone texts you or says something you genuinely don't understand. whether it's bad grammar or straight up ancient messapotamian, brand new sentence means you have no idea what they mean.
