When someone slides a gnarly piece of school lunch cheese into another person's binder, and it winds up being a really big scandal for no reason and multiple people end up in lunch detention as a result.
"Hey bro, how did you guys end up getting lunch detention freshman year?"
"What, you didn't hear? It was Cheesegate, dude."
"What's Cheesegate?"
"Take a seat, my bro, I have a story to tell you..."
A hangry girl who drools over Instagram pics of food that has disgusting amounts of cheese inside of and all over it.
My niece is such a cheesegrubber, I found her passed out on the bathroom floor still holding onto her drool covered phone which had a picture of a Krispy Kreme donut grilled mac'n cheese sammie with nacho cheese sauce.
