I saw two guys joking around, the first one had had a Cheetos bag. Here is the conversation that took place between them:
First guy: Do you wanna little snack?
Second guy: Yeh, actually, it's one of my favorites. (He took the whole bag.)
(The guys kept chatting for a while ... and the second guy was enjoying the Cheetos in the meantime).
First guy: I think you're probably High, (laughing ...) you just camping on the Cheetos.
Second guy: (Laughing out loud) Hahaha.
I know what camping is, and based on that I would guess camping on foods means to keep eating while you're allowed for tasting only? Am I correct?
