If it was Coy i wud look stupid saying its for 7x-10x wouldnt i LOL :D
Becoz it is COY R you can have an acronym which uses Coy along with R
Take for example FUNZ or MAYF
Now Fun is a word Z can be Zone => Acronym for Fun Zone, better than FNZN (which can be anoher acronym but a crappy one), therefore you are actually using Fun as a dictionary word attaching it to another Character.
Similarly MayF, BayM, CryC etc etc etc.
