jackbag
A part of the brain that stores all the stupid stuff a guy does when he’s trying to get off. The bigger the jackbag, the more ridiculous the stuff he does.
My brain’s jackbag is full of stuff. Like when I tried to balance on a chair and fell into a bowl of cereal.
My brother’s jackbag is huge. He once tried to text his crush during a math test and got caught.
My dad’s jackbag is so big, he once tried to use a cheese grater as a phone.
