Fangs up!
The "gang sign" created by Gabe Saporta, lead singer of Cobra Starship (Snakes On a Plane, Guilty Pleasure, The City Is At War) used to pump up the band's crowd; Involves the middle and index finger of one hand being bent like a hunched over peace sign, and the other hand covering the top of the first hand, so as to make it look like a cobra's collar and fangs.
