Mumford and Sons 

A band who's name sounds like "White boy shit."

Guy: "What's the name of the band tonight?"

Crew Member: "Mumford and Sons"

Guy: "That sounds like White boy shit."

Mumford and Sons 

A band that tries way too hard to sound 19th century Irish. Like Murphy's Oil Soap, the band has a name that your father recognizes but has never knew was a band. A typical British band that overplays their accent to break through the music (typically you can't hear British accents in songs). A bunch of 40 year olds acting like they're from some obscure town in Northern England 1858.

Pimple-faced teenage who works at McDonalds: "Hey Dad, can I have a few bucks for Mumford and Sons"?

Angry Father in a white t-shirt washing his car: "Sure, son. Just make sure you get you get the largest bottle you can. I need these tires to SHINE!"

Mumford and Sons-ing 

The acts of obsessively searching, listening to, and stalking the fabulous band Mumford and Sons.

I didn't study because I was Mumford and Sons-ing.
