When you send an email to a group, and someone on the grouplist has to write back to the group and 'dominate'. They have to get the last word and come across as the most superior in the group. Like when a dog humps another dog to dominate it.
Look at that reply. Dwight email humps me every time I send instructions to the team. He's such an insecure ass!
by definition humping a fine ass female while playing the sickest guitar notes known to the human race. Mixing humping and hendrix abilities into one and uncontrollable urge. Usually performed by wanna be rock stars. Note most of the humpers do not reach hendrix hump status.
"i dunno whehter the girl is louder or the guitar, that boy must be doing the hendrix hump."
