Preheal 

In MMOs when you have such a pro healer in your group that they're able to anticipate the damage another character is about to take and initiates a heal before the damage is actually inflicted.

First attributed to Los of Sentinel Guild while pulling massive mob trains in 2Moons.

Preheating the Oven 

A mental state of anticipation, specifically which occurs after one has consumed a marijuana edible, and before feeling baked.

“Are you fucking high??” “Umm, no. No, I’m just preheating the oven, dude. I only had that edible 20 minutes ago.” “Well then you’re just dumb. Also, nice Phrase, thou hast.”

PreHeated Oven 

Having your woman eat lots of hot or spicy food with the intentions of anal intercourse later in the evening. A woman can tell when she is prepped and ready by the warmth of her flatulence instead of the odor.

Dave noticed Sally force down two ghost peppers, he was excited to feel the warmth of her PreHeated Oven later tonight.
