flaming fart of doom
It begins as a rumbling feeling inside your stomach. You think it is nothing but then your ass starts to burn and flames shoot out of your ass at a very high speed and that is when you need to quickly run to the bath room before you kill everyone with in a 10 mile radius.
"Oh my Gosh I just had this flaming fart of doom all over the side of your wall and I need a power washer."
