A nickname created for Rawan because she is great, amazing, smart, adorable and (obviously) gorgeous. One person thinks she's literally the most perfect girl. Some people were tired of stating the obvious so they decided to create that nick name.
Have you seen how amazing and beautiful she is? She's ragorgeous
many examples: "that party was sooo rageous", "margarie, this martini is simply rageous" and of course "buffy, ur attending yale, can't u get an A for one quarter?? realy its just rageous!!"
