I feel like I'm at the height of my jump while y'all pivotin'

from Royce Da 5'9" – Gone (Return of Malcolm) Lyrics on Rap Genius

Meaning

Royce is steadily peaking (at the height of his jump) while all other rappers are moving in circles (pivoting). this line is tied together by a basketball metaphor (pivoting and jumping are both integral parts of playing basketball)
Sometimes pivoting can be better than jumping tho
