Proceding to the act of hot-karling involves one of the following:

1. Any part of sex in which faeces from one partner is found on the other, regardless of the technique. NOTE: the action of defecating on one's self may not be regarded as a "hot karl" but rather as "soiling yourself".

2. A form of assault in which the assailant procedes to fill a tube sock with his own faeces, ready to engage in fierce guerrilla.
1. While you were sleeping, I snuck into your sister's room and hot-karled her.

2. Brandon is such a moron, let's hot-karl him after school today.

"Hot Karl" is a slang term for sex which involves feces. Such variations of a "Hot Karl" are having a bowel movement in your partner's mouth, the female partner giving the male partner fellatio after he has had anal sex with her, or when a parter has a bowel movement on the other partners stomach (usually, the partner getting boweled on has Saran Wrap on his/her stomach).
My wife and I experimented with the Hot Karl, wow do I love the taste of my woman's shit.
