When you shit in a sock and beat someone with it.

When you eat dirt for the first time and leave your family to build a shack in the woods

The act of defecating on another's forehead with only a piece of cling wrap separating the feces from the forehead. Similar to the hot karl and the cold karl.

To shit on your partner's chest, wrap them in cellophane and then give them a hug. The heat of your feces produces a pleasant warming sensation. A hot karl, but just a few steps more.

It's when you take a shit in a sock and then smack someone in the face with it.

A Warm Karl is when you take your fecial product (Shit) and put it in a cup. Then you piss in the cup to the top. Once you have filled the cup with your shit and piss, you fit the cup on your erected penis. Once your shit and piss has soaked into your pubes and penis, you remove the cup and insert your smelly penis into a wrinkley ladys bum. Then you rape her bum until she has her period on your face. Can also be used in masturbation.
