It seemed to fit from what little I know of the players in the situation -- and the snarking on the other club just seems to be a childish "lookit how dumb they are!" thing rather than picking on them individually.
Meh, I don't even know who the 'suoh' chicks are aside from the time when Flora tried to snark them/bash them on the ED forums. That's why I didn't think it would be Pinkachu cause when someone showed her and I this (the screencap), we asked who the 'suoh club chicks' were and the person we were conversing with said they didn't know..
I just posted this cause I thought it was funny someone had called out the other girls; flora, iris, and onigiri. =/
