From https://en.wikipedia.org/wiki/V_sign#Origins

> This origin legend states that English archers believed that those who were captured by the French had their index and middle fingers cut off so that they could no longer operate their longbows, and that the V sign was used by uncaptured and victorious archers in a display of defiance against the French.

I guess that's all the keywords needed in order read the original comment fully.

It's only flicking the v's if the fingertips are pointing upwards, fingers are apart, and the back of the hand is pointing at the person you're gesturing to. We also call it the "reverse peace sign" as it's exactly like that but with your hand pointing the opposite way. Pointing your hand parallel to the ground like you would use scissors is nice and clear as scissors.
