Lush

The new 'fresh'. A go-to word that can be used to describe any noun or verb which the speaker finds particularly rich in flavour, aesthetic or sound. It is used particularly in Jazz, as a tribute to Billy Strayhorn's composition "Lush Life" and the album by John Coltrane of the same name.

"Dude, check out the lush chords that Gamran is layin' down."
"Pretty lush garden you've got here."
