EDIT: Jacky, it was not meant as something mean or bad. It was more of a joke and laughing with him not being mean to him.
To "Rib" in English means "to jokingly give a hard time".
I'm very happy to see R2 be so popular! That means you have a fantastic design and I hope you know that!
Also looking back at R1, I'm not sure if I want to edit my order to have a different color bottom. I know I want the grey top, but something about having that purple bottom seems kind of cool. Or even just a black bottom. Any thoughts?
