When you smoke weed and don’t feel like you have the munchies, but if you start eating, you can’t stop. Having munchies from smoking weed without realizing it. Not feeling like you have the munchies from smoking pot, but you do. (AKA silent munchies, hidden munchies.)
I smoked some super boof and got the ninja munchies. I wasn’t very hungry, so I poured myself a small bowl of potato chips. Before I knew it, I had finished off a large pizza, the whole bag of chips, a quart of ice cream

The name of the sexual act in which raucous sex is performed, and recorded, while other people are asleep in the room...the key: no one must catch you.
