No, she did it on purpose because Ame had just said something about "meese" being the plural of moose, which was something that was associated with Senzawa. I don't have a clip or a timestamp (if you search "gura rebecca" in youtube
the vod comes up) but I remember she says something like "Does chat ever call you a name that isn't really your name? Like, idk, Rebecca?" definitely on purpose.
