How does one explaining the meaning of the G#6b5 Chord to another with little to no musical background of Chords?
First, you find an intelligent name for the set of notes, not something dreamed up either by someone clueless, or with the intension of deliberate obfuscation.
You have the notes G#, B#, D, E#.
Now respell them as something that looks as if it might be related to C major: Ab, C, D, F.
So this is either an F minor 6 chord, or D half diminished seventh.
If you can't "explain the meaning" of either of those in C major, you need to learn what a II-V-I chord progression is.
