The result of a particularly large, high pile of shit in the can causing you to sauce up your fingers whilst going for an ass wipe.
I only had five minutes before my lunch break was over, so I wiped fast and got out of there. It wasn't until I shook my boss's hand that I realized I had passed him a couple chili fingers.
When a female is in a doggy-style position, warms a hot dog in her vagina, places a hot dog bun at the exit of her vagina, then squeezes the hot dog into the bun while excreting diarrhea simultaneously, which creates the "chili" on the hot dog. Eating it or feeding it to another is optional, yet preferable.
