A search of mancessory on Urban Dictionary proffered two results:

Manccessory: A male companion to a female. They can be seen together almost all the time. Usually they are dating.

Mancessory: Metro-esque accessories that men utilize when provoking the approval of hip crowds.

Somehow, neither definition seems to do the surge of accessorized men I've noticed justice. The mancessory is subtle. Like these Danner laces on a pair of work boots:

or this canvas Herschel pack:

Well done men of Portland. Well done. You do the mancessory proud.
