there guitar
n.— «This summer, Crane will give his own Sermon on the Mount. For the month of June, in addition to playing what he refers to as the “there guitar” (similar to how e-mail users call paper correspondence “snail mail”) in his own New York-based band, Crane will visit 15 U.S. cities as emcee of the first official “Aireoke” tour.» —“Air To The Throne” by Ayeli E. Rodriguez in Harvard University Harvard Crimson (Cambridge, Massachusetts) Apr. 20, 2007. (source: Double-Tongued Dictionary)
I must credit this term to Mike Wolf, music editor of TimeOut New York magazine. He suggested “there guitar” as the physical alternative to “air guitar,” so I must credit where credit is due.
Thanks
