This phrase can describe many people we have the pleasure of knowing and have to deal with on a daily basis;
Such as, stingy ass pricks who wouldn't loan you a dollar to save your life AND EVEN IF THEY DID... there would be 70% interest.
Aswell as "no bullshit" parents who force their kids (and other people's kids) to act like good fucking Catholic school boys with consequences of "a knuckle sandwich" and or "tanning your hide" in tandem with threats like "If you keep it up like this, you won't be able to sit for a week!" or " You'd better watch your smart mouth buster!"

A man who messes around with other men, but no one would ever know by looking or talking to him. Used by gay black men to identify masculine gay men or DL Brothas.
