a coin purse
A coin purse is like a man's scrotum. It’s where you keep your nuts and your coins when you’re too lazy to put them in a bag.
My uncle's coin purse fell off his bike. He yelled, 'I lost my nuts and my dignity!'
My brother's coin purse was so big, he called it 'the nut fortress.'
My cousin's coin purse got stuck in a door. He screamed like it was a horror movie.
