Looking at someone's junk like it's a free buffet and you're the only one who knows about it. It's creepy, weird, and probably illegal.

I got caught gafooning at the bus stop. The guy looked at me like I was crazy.

My brother was gafooning at the gym and got kicked out.

I was gafooning at my math teacher and got a detention.
