81-year-old Warren Buffett -- one of the richest men on the planet -- got downright gangsta at the grand reopening of Jay Z's 40/40 nightclub in NYC last night ... throwin' up the Roc-a-Fella sign ... like a boss.
Jay and Buffett have been friends for years -- and appeared on the cover of Forbes together back in 2010.
