The G#m/D# chord is a G# minor chord, with the D# (the 5th) as the bass note.
The G# minor chord itself has a dark, melancholy sound. Playing the 5th of the chord (in the case of G#m, the 5th is D#) as the bass note, can make the chord sound even more dark and dramatic, even if it is only a subtle difference.
The chord is also referred to as G sharp minor over D sharp, or G#m ‘slash’ D#, or simply, G sharp minor with a D sharp in the bass.
Technically, the G sharp minor chord with the D sharp in the bass is a second inversion G sharp minor chord.
