acoustic game

A game that requires no electronic components. The term has been adopted by independent game designers as a way to distinguish a game as being non-electronic, without implying that such a game is "missing" something. Acoustic games range from ancient games like Chess and Go to modern games like Carcassonne and Settlers of Catan. The terms can also be applied to non-electronic versions of electronic games, like World of Warcraft: The Board Game.

"On a rainy day with close friends, I'd much rather play an acoustic game like Fluxx, Poker or Chinese Checkers than play video games."

Acoustic Soul 

Acoustic soul music originates from soul and gospel music and played acoustically as the name suggests. Acoustic soul is oriented toward spiritual inspiration, but played without use of powered instruments. The only power in Acoustic soul music is the power behind the lyrics and heart and soul of the artist who sings this amazingly complex and heart felt genre of music.

Have you heard Laura's acoustic soul music style? She sings like an Angel.

acoustic guitar guy

anyone who grows out their beard and only showers every other day. You would most likely see an acoustic guitar guy walking their skinny bikes around bus stops with their hand-made satchels and loose comfortable clothes such as: wool caps, anything from urban outfitters , usually reek of marijuana , and may have a dog and of course, an acoustic guitar. Although they are called acoustic guitar guys, they might not always have an acoustic guitar.

Bus stop
"acoustic guitar guy": Hey bro you have any spare change for the bus?
guy: no i gave it to the other acoustic guitar guy
"acoustic guitar guy": thats cool man
guy: ya sorry
