Ninja Bear

First seen at the Edinburgh Festival and worn intrinsically for banter, one can become a Ninja Bear by wearing the correct eclectic attire. This encompasses a furry-eared hat and a ninja sword of any description. Further items are permitted, the usual being a pair of glasses.
The Ninja Bear is a smooth operator whose habits are far-reaching and far-fetched. These include drinking with abandon, reckless nights of debauchery and kissing fit people.

The Ninja Bear was wasted last night, it was awesome. I pulled this fit girl and was thrown out of that watering hole for laying hands on a motherfucker, who was trying to ninja the hat.
