A reversed [[v]] gesture. With the inward V, the [i]back[/i] of the hand making the sign faces outward at the viewer or recipient (the opposite of the standard V, which instead has the [i]palm[/i] facing out).

The British use this gesture as their equivalent to the [[middle finger]] gesture used by Americans. If the character also puts their tongue between these fingers, it can be a [[cunnilingus gesture]] as well.
