Jackasss
A Jackasss is someone who doesn’t know the meaning of the word ‘stop’ and will keep going until they’re completely out of breath.
My dad is a Jackasss. He ran around the block screaming like he was in a marathon.
My friend is a Jackasss. He tried to dance on the ceiling and fell into a pile of pillows.
My brother is a Jackasss. He jumped into the pool wearing a hat made of socks and then yelled at the cat.
