When you creampie a girl but it smells really bad due to your stinky cum. Often caused by an unhealthy diet.
"I gave this bitch a filthy stinkpie last weekend, I've been eating way too many flamin hot cheetos"
"All the guys in the quidditch club are so fortnite."
"I was at the function but there were so many fortnite heads, I just had to step."
