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.

"acoustic guitar guy": thats cool man

Profile of an acoustic guitar guy: The AGG can be found most often at college campuses and teen camps. The AGG is under the impression that he's very gifted when it comes to playing guitar, but in actuality is quite bad. He attempts to cover this up by singing and occasionally flipping his long hair, so long as it's not in his favorite hairstyle, the man-bun. His rolled pant legs and flip-flops are a desperate attempt to communicate that he doesn't care. The ultimate success to an AGG is acquiring a group of girls with low self-esteem and no musical talent, so that they are unable to recognize that he is really not great at guitar.
