A hand signal used to shut everyone up. It is made by pressing ones thumb, pinky, ring finger and pointer finger together, and sticking the middle finger up in the air, so that it looks like a unicorn. Should only be used if Silent Coyote
is ineffective. Otherwise it's just obnoxious.
The teacher held up a Silent Coyote, but the class kept talking. After about five minutes, she grew impatient, and busted out the real guns.
Teacher: *SHUT THE FUCK UP UNICORN*
Class is silent.
