A term used during drinking when a "razor" (a drunk individual who is extremely aggressive and loud) starts wildin' out and causing issues. They will often verbally and physically begin attacking the people around them, including but not limited to their friends, staff, and strangers looking in their direction.
Man you see that razor razoring, we ain't drinking with her no more.
I don't drink with Kesha anymore, she's always razoring when we drink. I don't got time for all that drama.
