Hey @asvpxrocky & @ActionBronson thx for the shout out on "1Train." Not sure what it means, but let's blaze one & talk about it some time.

You see us scrambling, selling Susan Sarandon
The other half of the lyric is either a reference to c0caine, as in "selling that white girl," or weed if it's a reference to the 1998 movie Stepmom in which Sarandon's character smoked medical marijuana.
A while later, Susan Sarandon heard the line and was honored for the shoutout while not fully understanding it's meaning.
