Song Help Request Name of chord G with hammered 5th fret

Hey folks,

What would you call a chord that is a basic G shape but imagine hammering on the 5th fret, 1st string (D)

It is essentially 2 x G and 2 x D notes

The sheep chord thingy doesn't give it a name and I am curious if it has one.

Any chord that has the root and fifth without the third is generally called a 5 chord. So in this case it is a G5. Five chords have an open type sound since the third of the chord tells you whether it is a major chord or a minor chord ( G major = G,B,D - G minor = G,Bb,D )
