Call him Shaquille O'NEILL ... 'cause the retired NBA Big Man hit the ocean hard in Florida this week ... with his super hot girlfriend by his side -- and TMZ Sports has the pics.
Shaq and Laticia Rolle were spotted in Cocoa Beach, FL on Tuesday by Louis Barr Photography ... splashin' around on the beach like a couple of teenagers.
FYI -- Shaq and Laticia have been hangin' out a lot this summer ... probably safe to say they're dating.
Soooo ... congrats!!
