Galloping Coyote
This is when you annoy your friends by sticking your finger up their butt, and they run around like a looney person, screaming and yelling.
At the mall, my friend did the Galloping Coyote to me, and I ran around like a maniac.
During dinner, my dad did the Galloping Coyote to my mom, and she ran around the kitchen like a crazy person.
My friend stuck his finger up my butt and I ran around the house like a wild animal.
