verb
slay
SLAY/sleɪ/
To kill someone violently.
In the final battle, the hero slays the tyrant.

Etymology
Old English slean covered both striking and killing with a weapon. Today's sense of impressing greatly connects with the long-established meaning “overwhelm with delight,” rather than only with literal killing.
In context
But if you can slay it and sing all the words perfectly, then your opponent gets sprayed in the face.
