As Inny demonstrates here, this is the classic way to complete the flick with the fingers not pointing 90 degree's up but about 20 degree's further back. You can also purse or bite down on your lower lip after saying somthing like "I dont know, I dont know, vhat you arre saying!" or "she vas so sexy, oh my god". Mr. Bubbles, accross from Inny, is demonstrating the reverse flick while saying "look he is so sexy yaar".
