A guitar that has 12 strings, 3 bass strings, 3 tenor strings, and 6 octave strings that pair with each string. Each octave string is tuned to the same key as it's other string, but also remain an octave higher. They create a rich and powerful sound that pairs good with loud and forceful singing, and is commonly used by buskers and professional performers. All tunings of course work with these, but the common and most effective tunings are standard tuning, and are commonly tuned to key of D, C, and B, tuning.
A famous and very talented performer, Lead Belly, used a 12-string acoustic guitar as his signature instrument, and usually had his guitar tuned to Standard B tuning for a wide range of songs and notes. He one of the most influential guitar players, and introduced many people to the 12-string.

"She is acoustic"
by anonymous17372927 November 6, 2023

A online term typically used to refer to an autistic person, commonly in a condescending or derogatory manner. People often use that word, as well as “restarted”, in place of the R slur. Some autistic people may be irritated by use of these words to describe them if they post something featuring them displaying their autistic traits, so try not to use that word if you do not know how the person will react. (I say this as an autistic person myself.)
E.G: “If someone calls me “Acoustic” again, I’m going to punch them in the face.”
