Gadhafi-ing
One friend sticks their thumb up the butt of another friend, like it’s a fancy handshake. They shout ‘Gadhafi!’ or they put the thumb on the seat right where the butt is about to land.
At the gym, my friend did this to me during a workout. I almost dropped my weights.
During a car ride, my brother did this to me. I yelled so loud the driver stopped the car.
At a party, my friend did this to me. Everyone clapped and took pictures.
