Have you ever popped champagne on a plane, while gettin some brain
Whipped it out, she said "I never seen Snakes on a Plane"

from Kanye West (Ft. T-Pain) – Good Life Lyrics on Rap Genius

Meaning

Now that he lives the good life, Kanye now drinks champaigne and gets oral sex (which brain is slang for) while flying in planes.
“Snakes on a Plane” is referring to the Samuel L. Jackson film (also meaning his dick)

Hopefully the girl won’t be tired of the motherfucking snake on the motherfucking plane

“Popped champagne” is also a double-entendre referencing ejaculation.
