What exactly did the Ying Yang twins mean by “Whistle while you twerk”

[King]

They literally tell you what they mean in the hook right after they say whistle why you twerk

They never explicit define what "p*ssy farting' means

Is it the sound of the cheeks clapping?

Queefing??

Regular farting???

Or even physically whistling with the p*ssy lips whilst twerking????

These are the questions the people need answers to.
