They say success is the best revenge
So I beat DeShay up with the stack of magazines I'm in

from Tyler The Creator – Yonkers Lyrics on Rap Genius

Meaning

Brandun DeShay is a former Odd Future affiliate who was scorned by Tyler due to beef. Since then, OFWGKTA has blown up and been featured in magazines like Fader and Spin. DeShay has been successful in his own right though, producing tracks for Dom Kennedy and others

“Success is the best revenge” is a common phrase. Other variations include “eating well is the best revenge, and "living well is the best revenge”

Because “success is the best revenge” Tyler was focused on or recognized by magazines. Revenge is usually thought to be directly physical, so Tyler hypothetically beats him up senseless with those magazines (his success).

Deshay responded to this diss by mocking it on his song “FTW!”
