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.”
