Although some individuals get stuck with the label, people often call someone a dumb ass when he has done something that they consider idiotic. Synonyms for the word “dumb ass” include “block head,” “knucklehead” “bonehead,” “dullard,” “pillock” and “stupid person,” according to The Free Dictionary.

Dumb Ass
The nickname or noun dumb ass is often meant to make people being called the name feel like they are below their name callers in educational level or social status. People who have committed stupid acts or said nonsensical things may laugh at being called dumb asses, especially if the individuals calling them that are their friends. They may return the favor when their friends do something that their group of friends or society views as being stupid. Although dumb ass can be a playful term used between friends, it can also hurt somebody’s feelings if it comes from a person he doesn’t know very well or doesn’t respect. People need to be careful when using the word “dumb ass” because it can be just as hurtful as calling someone “stupid” or “unintelligent.”
