Antonio Brown used offensive language on his social media page yet again on Wednesday night ... calling Jared McCain a homophobic slur during the NBA draft.
The former Pittsburgh Steelers star typed out the f-word as McCain -- an ex-Duke guard -- was being taken by the Philadelphia 76ers at No. 17 overall.
The post -- which was made on top of a McCain TikTok that showed the hooper dancing around with a shower cap and painted nails -- appeared to be an attempt by Brown to be funny .
