Irish Session 

A marijuana related assemblage where only those bringing thier own lighters are allowed. Passing or borrowing lighters is strictly prohibited and can result in an Irish themed ass whooping. Anyone can join, as well- providing they're nonchalant about it.

John was acting like a fucktard and trying to join our irish session without his own fire.
