Is another name for artisanal beer. It's derived from that stupid band Mumford and Sons whose fans tend to be of the hipster doofus crowd who wear bowlers and suspenders , have handle bar mustaches and top knotsand tattoos of pennyfarthings. They tend to drink only fancy beers out of flip top bottles.
Hey Cny pass me one of those mumsies, I hate these banquet beers.

Hey Geebs, these fancy mumsies will drink great on the back of the boat. Fuck yeah.

H9 is on beer duty, put those mumsers in the locker room, they will be awesome when we get off the ice.
