Rap Star O.T. Genasis -- Offers Coco-Concert ... For Golden State Warriors

Hip hop star O.T. Genasis loves one thing as much as the CoCo ... parades ... 'cause he tells TMZ Sports not only does he want to go the Golden State Warriors victory parade, he wants to rock the mic!

O.T. stopped in to chat with the gang on "TMZ Hollywood Sports" about the newly crowned NBA champs ... and how they have used his hit song as their unofficial anthem the entire season.

How much does O.T. appreciate the love the Dubs have shown him? He tells us he wants to return it ... by recreating the magic for the team at their victory parade tomorrow in Downtown Oakland.
