When you poke somebody particularly hard in the arm with your index finger whilst shouting at the top of your lungs "devil finger!!!!"

NOTE: a "double devil finger" can also be applied, particularly if the person is a bit of a bastard; in which case you simply repeat the actions above whilst using both index fingers
Person 1: *sits down*

You: *pokes in the arms hard* "DEVIL FINGER!!!!"

Person 1: *glare*
