An upward motion with the hands that some DJ's make as if the knobs on their mixer are hot to the touch.
We thought the DJ was awesome until he started hot knobbing and ruined the vibe.
She thinks hot knobbing makes her a cool DJ but it just looks ridiculous.
When a pro DJ is hot knobbing you may not even notice it but when a newbie is hot knobbing he is probably not even actually changing anything.

When you rub 'deep heat' on your balls, and you get that most amazing sensation.

Basically how I lost my virginity

It's when you go to the bathroom during 9th period and then a spooky man named Quanny jumps onto you and penterades your ass with his small penis as he anal rapes you in the stall not caring what your ass looks like up until he let's you fuck him as well.

Quanny is fucking weird tbh but anyways that's how I lost my virginity.
Yo, I got news that my friend was in the hot diggity knob incident! It was crazy!
