Appendicitis, hey you know that useless little nib on your colon, its now turned into like a pimple on your intestine, but instead of puss it's puss AND poop, and if it rupture it blows poop and blood and E.coli all over your insides.

That's the first time I see it described in a positive way.

Most of the time even when medics describe it as tl;dr you're walking around them boom dead.
