kaboon
Kaboon is the lid you slap on a bottle of chocolate milk or eggnog like it owes you money.
I opened my chocolate milk and the kaboon was stuck on so hard I thought it was a curse.
My cousin tried to drink eggnog with the kaboon still on. He looked like a confused raccoon.
I asked for a kaboon on my milk and the guy at the store looked at me like I was a lunatic.
