Don't pity the loser ... especially when the loser's made more than $100 MILLION ... so says Riff Raff.
The rapper (and NBA super fan) was out in NYC when we asked if feels bad for Kevin Durant, after the OKC Thunder failed to close out the Warriors, despite big leads in Games 6 and 7.
Long story short ... Riff says Durant's still his homie -- but it's hard to feel bad for a guy who's still RICH.
Also, Riff says it's not entirely KD's fault -- blaming Lil B for sticking him with the Based God curse.
