ear wax method
You dig your finger into someone's ear, grab a chunk of wax, and stuff it in their vagina to see if they have a disease. If they squirm, you know they're messed up.
My friend stuck my wax in my girlfriend's snatch and she was like, 'I'm gonna kill you.'
I used my brother's ear wax on my crush. He turned red and ran away.
I tried the method on my teacher and she sent me to the office.
