(noun, plural)
Records in any recordable form, of compelling events having taken place.
Not just any events, however - said events must be:
-outlandish
-fantastical
-neutral to bad
-difficult to believe for those not present
-able to be described as "gnarly" or "gnar-gnar"
Social Media is the most commonly used medium for the recording of such gnar events, but it is not reliant upon this medium. Journals and diaries are another common form.
Brian: that was a crazy show last night!
Rob: I know right? Can't believe we got out of there in time.
Brian: oh yeah we sure did. That swarm of rats seemed more ready to party than we were hahah
Rob: omg so gnarly dude. This is definitely going down in the Chronicles of Gnarnia.
Brian: lol already on it
Rob: shred the gnar
