Idgit = idiot
If this story is all true, I suspect you have been the target of a joke.
As illustrated in the following quote:
"Well, ye air a skeery critter! " he said, contemptuously. "I hain't goin' to hurt him, Uncl' Gabe, but he must be a plumb idgit
, a-talkin' 'bout folks to thar face, 'n' him so puny an' spindlin'! You git!"
