I should've went and cut the grass
Snake ass niggas in my fuckin' face

from Kanye West (Ft. 2 Chainz, Big Sean & Marsha Ambrosius) – The One Lyrics on Rap Genius

Meaning

As the phrase goes, there are “snakes in the grass”. The idiom relates that there are sneaky and untrustworthy people waiting to take you down, always lurking just below your radar. 2 Chainz should have cut his metaphorical grass so as to expose the snakes and traitors.

Also playing off of the anaconda before.

Haters!
