Jason Momoa's Line Finger Tattoo In June 2014, Momoa got a tiny tattoo of a simple line on the back of his hand, above his thumb but close to his wrist. He shared a photo of the process on Instagram with the caption, "Home tats. Mahalo Tobias If anyone's in la and wants tatted up by my boy let me know he'll be working next week. Aloha j." The meaning behind this obscure design is unknown. Image Source: Getty / Jerod Harris
