Dumbass

A few days ago, I was in my bathroom drying my hair when Jake comes running in, shouting "Megan called me a dumbass". Megan followed close behind and told me "I did NOT call him a dumbass. He called me a dumbass". Jake retorted "I did NOT call you a dumbass. Stop trying to get me in trouble". And last but not least, Megan responded "I did not say dumbass. Jake said dumbass".

My reaction: "The next person who says dumbass is getting their mouth washed out with soap!"

I can't imagine where they possibly could have heard that word.
