ARF

An abbreviation standing for Adolescent Rat Fart. Someone who is an ARF is annoying, EGOTISTICAL, loud-mouthed, short-tempered, immature, and speaks with an entitled, undeserved authority about subjects they know little to nothing about. They may or may not be prone to dressing in a ridiculous costume while doing so. They are likely to overstate their own abilities while downplaying the skills and accomplishments of others. If you encounter an ARF, your only hope is to run away as fast as you can, and pray they don't take chase.

"Ugh, I just got off work. My coworker is a total ARF!"
