Squirting feces and projectile vomit simultaneously while urgently looking for a toilet.
After all those street tacos and tequila that old gringo turned in to a Dirty Pinwheel on the way to the bathroom.
someone who inserts a fidget spinner in their rectum for sexual pleasure.
"what are you doing tonight?" "oh nothing just dirty pinwheeling".
The Dirty Pinwheel is when you take one of those fidget spinners stick it up your ass and upon removing it, give it a spin so that the shit flies off of it.
My buddy's girlfriend left him after she got pink eye from the dirty pinwheel he gave her last week.
