eagle fart
When you drop a massive butt gas on someone you dislike, just to make them feel bad. It's not always loud, but it's always smelly and usually makes people run away.
I did an eagle fart on my brother during dinner and he had to go outside and vomit.
My friend let one rip in the library and the librarian gave us a warning.
I did an eagle fart on my crush during our first date and now we're both enemies.
