Mostly everyone is wrong, a 'hot carl' is the act of putting seran over the face and taking a dump on it. Anal to oral is called a 'rusty trombone', dumping on the chest is a 'Cleaveland steamer', and anal to tit fuckin is a chilli dog. If you have the squirts and can attain maximum heat and force a hole through the seran and onto the skin/mouth then you are awarded extra points, carl would be proud.

A jack off buddy (from 'cum' /'come', meaning 'semen', and 'companion'); a friend that you get together with for sessions of solo or mutual masturbation
Variant of: cumpanion (from 'companion' & 'cum'); jack off buddy & wank bud & JO buddy
Similar to: fuck buddy

the act of putting seran-wrap on ones face and proceeding to take a hot steamy shit on the seran-wrap, thus letting them feel the warmth of the poo on their face.

Alright...A Hot Carl is done in 1 of 3 ways.
1st: You shit on your partners face.

2nd: You shit on your partners face who is sporting a piece of saran wrap over it.

3rd: You shit on to a glass table while your partner lays down underneath it.

All are varying degrees of hardcoreness!

A Hot Carl is performed correctly when you line the recipient's mouth with saran wrap and then pinch a loaf directly into their awaiting open orifice.

A Sloppy Carlson occurs when the loaf is hot and runny (diarrhea) and forces a hole through the saran wrap, mmm.

You put saran-wrap over your face, while someone shits on your face, so you can feel the warmth of there poo.

THE REAL DEAL, FROM THE HOT CARL MASTER HIMSELF

A hot carl is when someone puts seran wrap ontop of another person's face and shits on it. This creates a warm tingly sensation that i like to call a piping hot carl.
