fabm
When someone is so annoying they make your mood go from okay to exploded.
My brother is a fabm. He texted me at 2 a. m. with a meme and a question about my ex.
My teacher is a fabm. She gave me a pop quiz and a side-eye.
My neighbor is a fabm. He blasted music at 7 a. m. and asked me if I wanted coffee.
