slay
celebratory, empowering, camp
the one-line answer
To perform excellently or look amazing. Can be used as a standalone reaction.
Slay comes from ballroom and drag culture where it meant to perform with excellence. It moved into Black and queer internet spaces, then went fully mainstream. Saying 'slay' at something means it is impressive, excellent, or confident. As an interjection it just means 'yes, excellent, keep going.'
