Kind of like a mouthgasm. It's when you haven't had any nicotine in a while, then you get some, and the nicotine shock makes you feel very good.
Person 1: I had a nicotinegasm the other day.
Person 2: What's that?
Person 1: It's like when you haven't smoked in days, and then you get some nicotine. It's almost orgasmic.
