Gestures of victory or insult (1-5)
I believe the answer is:
v-signs
'gestures of victory or insult' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for v-signs that I've seen before include "They show victory, or insult" , "Gestures of victory or insult" , "They can signal victory or insult" , "They display victory or contempt" , "With palms pointing outwards, they signal victory" .)
