When a old lady fills her mouth with warm oatmeal and proceeds to shove your cock in her mouth and swish it while sucking you off.

Devin: "That old lady behind the counter is kinda hot".
Jose: "Do you think she like knows how to suck it?"
Devin: "Shit! She has been around forever she probably invented the -Oatmeal Swish- she's so old".
