Look, I’m east side them haters 90 going west
My niggas pumping so much bass, muthafuckas going deaf
Weezy F, I'm east side them haters 90 going west
My niggas pumping so much bass (Pump that bass)

from Lil Wayne (Ft. Big Sean) – My Homies Still Lyrics on Rap Genius

Meaning

Lil Wayne eastside flow makes the haters abandon their lives and take their crusty asses west, via I-90.

His team is so hot and pumping so much bass, that others can’t even compare and end up going deaf from YMCMB’s sick beats.

Interstate 90 is the longest and northernmost interstate highway in the US. It runs from Boston, MA to Seattle, WA.

The word “bass/base” is used two ways, referring to both low frequencies and the potent form of amphetamine

The word ‘eastside’ is also paying homage to Weezy being from the Eastside of New Orleans.
