A term that means nothing, but you create it with a group of people to use around a nosy individual that needs to know everything. Use it in everyday context, but when the nosy person asks you what happened...you ignore them or say nothing happened. You do not tell the person what it means and it drives them crazy.
When nosy individual is around:
Q: Did you see Jim last night at the club?
A: Yeah, what the hell?
Nosy guy: What did he do?
A: Oh, nothing. Green Beans and Garlic.
