Seeing as there are terms not everybody is familiar with (for example B-M and the word tsundere), some people tend to use it without understanding it (that's a big plus for B-M, showing that he's not like that ^_^ ).. I guess that maybe it was smth like a fashion to call all the characters tsundere..
I don't actually understand calling cahracters moe.. since the original meaning for moe was
such.. So naming a character - moe, is out of my reach ^_^
