F.A.D. (Firey Anus Discharge)
Feces that feel like your butt is being attacked by a flaming dragon. You get it from eating too much chili and not enough mercy.
My friend’s F. A. D. was so bad, he had to take a shower in the middle of the night just to escape the pain.
I had a F. A. D. so strong, my sister texted me and said I was ‘literally burning from the inside out.’
My F. A. D. was so bad, my pants caught fire, and now I have a permanent smell of jalapeños and regret.
