It can be used in different ways.
It is
difficult to give a specific
definition, however the examples will illustrate the words ‘
definition’.
The word is meant to be taken lightheartedly (context depending).
For example if I had just smoked a
joint and walk into a room full of
people and I feel like everyone is looking at me, I would say ‘I’m rigging out’
Or a similar example would be if there a member of the public on the
bus eating beans out of a can with their hands, I would think to myself ‘that is a
rig fest (festival) over there’ , or ‘that is a riggy thing to see’.
The gentleman I just had a passive conversation with (who spoke about deeply personal things without the conversation being led there) was, ‘a rig man’.
