Heat dick 

To smoke marijuana from a bong using a heat gun instead of a lighter or match. The effect is to vaporize, rather than burn the weed.

Hey bro, wanna do a few bong rips before we head out?
Nah man, I've got a heat gun so let's take some heat dicks instead.

Sudden heat dick meltdown 

The sensation in a man's penis when he needs to have a piss and thus walks inside in search for a toilet, but since he has encountered air warmer than that outside, he pisses himself.

Person: "Oh man, I was outside in the cold and now that I'm inside I've got sudden heat dick meltdown!"

Dick heat 

The heat generated from one's penile area

Whilst I was driving my car raju was holding my bottle of water between his legs. As he passed me my bottle, I could feel warmth at the base of the bottle. I exclaimed "Raju! I can feel your dick heat."
