Hairy sponge
You steal your friend’s sponge and use it to shave your junk in the middle of the night
I stole my friend’s sponge and shaved my junk at 2 AM. He woke up with a hairy mess.
I took my buddy’s sponge and shaved my nuts in the dark. He thought I was possessed.
I grabbed my sister’s sponge and shaved my pubes in the middle of the night. She was mad.
