jab shield
The thing you scream when someone near you lets out a fart. You hit someone and yell it so the fart doesn't come back at you. If you're the farter, you're trying to get someone else to deal with the stink.
My dad farted in the car. I yelled 'jab shield' and hit my brother. Now he smells like a rotten sock.
At the dinner table, my mom farted. I screamed 'jab shield' and hit my dad. Now he's the one who smells.
In the middle of a movie, my friend farted. I yelled 'jab shield' and tapped him. Now he's the one who stinks.
