Definition & Meaning of "butt farter"in English

What is the origin of the term "butt farter" and how is it used?

"Butt farter" is a crude slang term that likely emerged in late 20th–21st-century English as a straightforward, humorous insult, combining "butt" (buttocks) with "farter" (one who farts). The term directly labels someone who passes gas frequently or excessively, often to tease, embarrass, or mock them. It is primarily used in informal, juvenile, or comedic contexts, such as among friends, online jokes, or children's humor. The term is derogatory but playful, not meant for serious offense, and is generally considered silly rather than deeply insulting.
