Nixon finger formations (1-5)

I believe the answer is:

v-signs

(Other definitions for v-signs that I've seen before include "Gestures of victory or insult" , "They display victory or contempt" , "With palms pointing outwards, they signal victory" , "They can signal victory or insult" , "They show victory, or insult" .)

I've seen this clue in The Wall Street Journal.
