Talk:しう (SIU)/@comment-6433273-20191121153152

As various people explained in the song's comments, "しう" was likely chosen for the name cause it can be spelled out in romaji as "siu", which would likely stand for "SUCK IT UP" which is what the censored lyrics part is saying.

I'd put it in, but I'm not sure if it's been completely confirmed or is at this point, only speculation.
