Wkhan is the act of someone talking nonstop gibberish or unintelligently rambling repeatedly trying to either run out the clock on a meeting or trying to aggravate the other person into a state of daze. Making the second party loose all hope they had to resolve the situation.
Example:
Mike: Hey Joe did you get any traction on project x
Joe: no wajid kept taking until the time of the meeting ran out and did not address the situation.
Mike: I see so you got wkhaned.
