I felt the same way too. She basically started off her career trying to snag the coomer audience.
Nerissa: OMG I totally don't wear panties teehee
All of chat: I WISH THAT CAIR WAS MEEEEEEEEEEEEEE!!!!1!!
And I pretty much tuned her out from day one. However...she isn't so bad. She's been largely inoffensive in collabs that I've seen and I caught a solo stream or two and she wasn't going full horny. Just the occasional comment to keep her coombrained audience sated. That said, I still don't watch her much compared to the others. Bad first impression and all. But she's grown on me.
