Get a reilly mug for your buddy Manley.
Reilli in the most generalistic term would simply be defined by that of a star. Far out, burning bright, hot and unyeilding in an ice cold universe. She is cosmic. One of a kind. Dreams big. Pursues so much, and will eventually accomplish and conquer all. Loves turtles. Appropriate aliases are Riles McGee, and big booty Judy.
"Wow, do you see Reilli over there? She's glowing!!!!"
"Luminescent!!! So intelligent, though misunderstood, I'm enthralled!!"
"Ugh! She's so lucky, she's a star!"
