Double Bird Salute

Common:
The act of giving somone "the finger" by extending your middle and ring finger of either/both hands in rage. Gives the appearance that you have two middle fingers on the same hand.

Alternate:
Extending the middle finger on each hand as to give someone the finger with both hands.

Often called Flipping the Nixon (telated to Nixon flipping the peace sign overseas which is the same as flipping someone off, also because the formation almost appears to look like your flipping a peace sign).
