The "New Freezer" rapper was down in Tampa and got inked up by Tattoo MF Red ... splashing an assortment of purple and black hues to complete the piece on the back of his right hand.
Red, a go-to for celebs and athletes in the area, tells TMZ Hip Hop he got Rich's hand tat drawn up in a flashy 30 minutes ... in between his recording session at STB Entertainment studio and a radio interview he conducted.
Unlike some rappers paying tribute on social media, Rich's ink and love for Takeoff can't be misconstrued for clout chasing, as they got pretty tight over the years.
Takeoff was the one who actually taught Rich how to make it rain in the club, and they had numerous collaborations together ... never hesitating to go outta their way to celebrate each other's birthdays.
The last time we spoke to Rich, he fondly remembered those moments with Takeoff ... and he was also looking forward to the music he'd be making courtesy of his new multi million dollar deal with RCA.
Rich was recently in the studio with Takeoff's brother YRN Lingo ... who approved of the finished product and promises to drop a banger this Friday.
Long live the Rocketman!!!
