The act of forcefully defacating through the strings and into the body of an acoustic guitar, via the guitar's resonance hole. This abhorrent method of vandalism usually requires heavy practice and advanced physical contortion skills of the perpetrator. Usual suspects include perturbed musicians, hysterical fans, and the psychotic or inebriated. Named after the Gretsch "Jim Dandy" model parlor guitar, which are often the victims of this heinous act.
"Good lord, Terrance! What on Earth is that horrendous smell coming from the parlor?"
"Ol' Briscoe came in here last evening and Jim Dandied my new guitar! The gall!"
"The bastard! I knew it! I'd recognize the sulphuric brew of a Jim Dandy anywhere!"
A group of people that rolls 600 pounds deep, which is really no different than if one person acted like the 600 pound gorilla all by themself, it's just bullying spread around a group to fuck with somebody. Just like each person has an asshole, and to some degree is an asshole, a collective 600 pound gorilla has a collective asshole so that no one person has to take responsibility for being the asshole or the one who said this or that.
A sports team/organization that by all conventional metrics should not have success/wins in whatever activity, but somehow by apparent luck they find a way to win.
