Kabooph
When you let one rip in someone's drink just for fun. People say it brings a curse. The only way to break it is to do it back to someone else. Farting is the main way.
I Kaboophed my boss's coffee and now he's got a curse.
She Kaboophed my soda and I had to Kabooph my mom.
At lunch, I Kaboophed my friend and now he's laughing at me.
