PACHEM - A word that was clean and innocent until a bunch of brain-de

A word that was clean and innocent until a bunch of brain-dead 13-year-olds turned it into something gross and embarrassing.

My mom said 'PACHEM' and I had to go to the bathroom.

My teacher asked what it meant and I said 'I have no idea but it’s probably something gross.'

My friend’s dog heard 'PACHEM' and started barking at me.
