We really need a "huh" reaction of sorts because some people on this site say the most bizarre deranged shit
I just use the wow face for multiple reactions. you'll not know what I'm really thinking if I use the wow face, but it's ussually some level of wow positivie or negative.
It's also positive reactions, so you'll just have to guess. It's always a subset of wow. Could be wow this is amazing or wow that's cringe.
