Left stroke, right stroke, whats the best stroke
That stroke can smoke all down her throat

This is a reference to a classic line from Biggie Smalls “One More Chance Remix”…

“Right stroke, left stroke was the best stroke
Death stroke — tongue all down her throat.”
Way to pay homage to the “nicest MC!”

Here is the classic video!
