LaMelo Ball is vying to be the NBA's most tatted hooper ... the Charlotte Hornets star just got his entire back tattooed, and the space-themed ink is awesome!
TMZ Sports has learned the All-Star guard went to his go-to guy, Herchell L. Carrasco -- aka RockRollG -- at Pachuco Tattoo in Orange, California ... after months and months planning the huge tattoo.
Ball wanted to keep with the space-themed tats ... so RockRollG had friends Niz Carillo, Jorge Garibay, Juan Nambo, Jonas Aguilar, and Elvis Ramos help him bring the concept together.
