While we're talking of index fingers, I've noticed there seems to 2 main variances in flipping someone off (the bird-American style) (oh yeah babe, this is scientific alright !)
1. Three fingers folded against the palm and held in place by the thumb with index finger protruding full length
OR
2. Three fingers bent at the second knuckle with index finger extended alone from second knuckle and thumb aligned with side of palm
International versions vary but the general meaning is one of derision and disrespect.
How about a straw poll on versions------Oh shoot, I should have started a new thread.....................lets keep it clean OK
