Heat and Mass Transfer

An extremely nerdy euphemism for masturbation. Used mostly by engineering students.

Student #1: "Hey man what are your plans for tonight."
Student #2: "Nothing much. Just gonna study and then some quick Heat and Mass Transfer. Same as always."

White Heat

The warm flakes from a Krispie Kreme donut that melt into your hands.

Bro, did you just jerk off? What’s the white stuff all over your hand?
Nah man - that’s just some white heat. Ate a whole box of fresh Krispie Kreme donuts last night in bed. That’s why my trash can is full of tissues… to clean up the white heat.
