The word "
Jobby" coming from the Scottish for shit/poo, a "
Jobby Jabber" concerns the act of sneaking up behind a friend/foe while pressing both hands together into a "praying" position, then forcibly ramming pointed fingers up the (fully clothed) arse of said friend/foe, shouting "
JOBBY JABBER!". Remember to run away to avoid violent repurcussions; laughing is optional.
