Brush your hair with a house centipede

Exclamation, curse

1. Essentially a school/church friendly way of telling someone where to go. It's also a great alternative to say at work so you don't get in trouble with HR.

2. A way to end an uncomfortable conversation. The thought of using a house centipede to brush your hair is so disgusting it's a sure fire way to make your annoying friends shut the hell up

"Hey, Trish, wanna go hang out in the bathroom together? I have some things I wanna show you,"
"Go brush your hair with a house centipede, Melone!"
