When you are hotboxing a vechicle and roll down the window to let the smoke go but your friends are paranoid of the cops seeing smoke you would say "fuck the popo let the smoke go" as in saying you don't care the cops will see the marijuana smoke.
Miguel: Elici roll up the window the cops are gonna pull us over and see the weed
Elici: no "fuck the popo let the smoke go"
