They were misspellings by past article posters who were too excited to spell check what they wrote.
I wish I could find the original article, but it's kinda like this: someone once posted a very misspelled post, wiht huge mispelled "hugh", serious as "series" and a host of other rather random misspellings. For whatever demented reason, now if anyone misspells the word "huge" as hugh, we are supposed to respond with "SERIES" - showering follows.
I'm not sure about the showering part, we need a historian.
