Nappetizer

A) Noun. The final alcoholic beverage one consumes before losing consciousness. Usually associated with irrational exuberance and unwarranted confidence. After ingesting a nappetizer, most details of the evening must later be forensically reconstructed with the help of friends, as recall is impaired significantly.

B) Noun. A nightcap.

"Dude, that 7th shot of Jager was totally his nappetizer. What the fuck was he thinking?"

"Hey, baby -- why don't you come inside for a quick nappetizer? Plus we can play Guitar Hero..."
