How to Sign "Screw You"
To sign 'screw you', form a '3' handshape with your dominant hand by extending your thumb, index, and middle fingers while curling the others. Hold your hand in front of your chest with the palm facing down and slightly inward. Thrust your hand forward aggressively toward the person you are addressing. Make sure to use a frustrated, angry, or dismissive facial expression to match the strong emotion of the phrase.
