DeMarcus Cousins lost his cool … twice … and it cost him.
The NBA has fined the New Orleans Pelicans star $50,000 after footage surfaced showing him telling a fan to "suck my d**k" during Sunday night's game against the Lakers.
The league also references an incident where he told a heckler the following night to "sit your fat ass down."
On both occasions, Cousins was being heckled by rival fans. Both were away games.
Don't cry too much for DeMarcus … he's making $16.9 MILLION this season.
