Who is Aleksej Pokusevski — and what is the obsession with his fanny pack?

Aleksej Pokusevski, “Poku” for short, has the internet buzzing — but not so much about the NBA rookie’s on-court skills. Despite recording 19 points, four rebounds and two blocks across 32 minutes in the Thunder’s loss to the Detroit Pistons on Monday night, Poku’s fanny pack stole the spotlight.

In a post-game presser, the 19-year-old was asked about the contents inside his fanny pack after a reporter noted that fans were curious about his belongings. Poku rocked the beige-colored Nike bag while making his way into the arena. “I’m so sorry, I gotta keep it a secret,” Pokusevski replied, smirking. The secrecy has sparked a playful mystery among some Oklahoma City fans, who “need to know” what the Serbian star is carrying around his waist. Until he decides to share, or accidentally spills what’s in his bag, there are a few things to know about Poku.
