The act of sneaking into the orca inclosure at sea world and beating your meat while also pleasuring the orcas until both you and the orca sporadically orgasm at the same time causing the Rapture setting of the plot for This is The End by Seth Rogen.
Oh shit, I accidentally did a Dirty Carlo on Wednesday and now the world is over.
The Dirty Carlsen is the act of having sexual intercourse with someone (a man) in the "Dagli'Brugsen" in Gevninge, and afterwards running out on the road nude and thereafter stopping a car on the road, getting the driver to pull down the window and then you cum in their front rear window whilst saying "I have crippeling depression"
Guy 1 "Man i got arrested for pulling a Dirty Carlsen the other day"
While being held down by a dominant man, he fingers her anus and vagina simultaneously until she ejaculates (if she pees it is not a Dirty Carlotta but has another name), then while still dripping, sits on his face backward so that his nose is in her ass.
He was banging her good and it surprised him when she gushed on his hand and gave him a Dirty Carlotta.
It is said of the situation where a person has the bad luck to make contact with his testicles against an undefined surface or object, intentioned or not.
Given the nature of the word, it is more appropriate to design cases where the interaction is made with a moving object, for example, a ball.
Although it is extremely painful for the victim, it tends to be considerably funny to people who witness it.
Today in the baseball game the pitcher took a nutshot; the baseball hit him in the nuts.
Man, I just watched the funniest nutshot video ever.
