The Whitey refers to a Failed Handshake. As black people usually have no trouble with this phenomena, and white people are almost always the
culprit, the title is fitting.
When two people greet eachother, one person may go for a high five while another goes for the ghetto varation. The result is an awkward stew of
hand gestures, and
fleshy palm on palm friction.
The Whitey can also refer to someone completely missing the other person's hand, resulting in a re-try or giving up entirely.
