The word 'dumbbutt" is slang and minor swearing. It combines derogatory word 'dumb' with a demeaning connotation associated with a person's rear end or 'butt'. It is meant only as a put-down, a way to be nasty to someone else, and to act superior to the other person. Therefore, it is bullying and abusive, even if it does not use any major swear words.
