The Classic Finger. Every genre and fashion has its “Classic” : the old stand-by that never fails to do the job. This finger is the jeans and T-shirt of middle fingers. It’s the dependable Chevy of rude gestures. Its style is found in its lack of embellishment. Form over function. If you only have one go-to style of finger flip, this one is for you. A classic is never out of style.
What it communicates to the recipient: I hate you because you are hate-able. Go away.
When to use it: General use acceptable. At social events, in traffic, in line at the grocery store, with friends and family.
