Shareef O'Neal -- Shaq's son -- just revealed his second Kobe Bryant tribute tattoo ... showing off the ankle ink in a social media post Sunday.
The LSU basketball player had already gotten a calf tattoo to honor the NBA legend ... but O'Neal clearly felt that wasn't enough and underwent the needle for more Mamba art recently.
And, the new tat came out great ... it's a depiction of a famous image of Kobe celebrating -- and it looks real as hell!!
