Smoke hit they lungs, make 'em UFC Tapout
While smoking in the metaphorical crack house (the rap game) Pusha’s smoke (his raps) hit the other rappers lungs and made them tap out.
In the UFC when fighting an opponent there are two ways of winning;
Knocking that opponent out
Making them “tap out” to forfeit.
Hence Push made his opponents lose the “easy or soft way out”
