Draymond Green had no mercy on his newest Golden State Warriors teammate DeMarcus Cousins, trolling him even during his own birthday, as Boogie turns 28 years old.

It didn't take long for the two high-octane brothers to get haircuts and get on each others' last nerve, as expected.

Green was happy to roast Cousins on his fading hairline, while Cousins made fun of Green's lacking goatee — giving us a preview of the insanity that could unfold as two of the NBA's rowdiest players share the same locker room.

Head coach Steve Kerr recently received a contract extension and he is now expected to earn every penny of it by handling these two firecrackers during a long 82-game regular season.

Somehow, the Warriors have managed to remain together despite Green's highly-volatile antics and the addition of a perennial scorer in Kevin Durant, but time will only tell if Cousins' dose of TNT will be what sparks a potential explosion in Golden State's locker room.

If it does, it won't take long before fans Blame it on the Boogie, as he was the latest cog in an All-Star-filled Warriors team.
