Serebii = Probably the largest fan-forum of Pokemon on the Internet.
Joe = Serebii Joe, an English guy who created the website. Unlike Marriland or the kiddy fiddler who runs Bulbapedia, I probably would have a go at him.
Sticking her nose = Having a go, taking the plunge, doing the bould thing, intercourse.
Pantsu = Knickers.
Anyways, it's ****ing Becky. Becky always says stupid stuff like that to get people to pay attention to her, which means that she hasn't been getting much lately on Serebii. Then again, as Becky was also one of the few people to ever provoke a serious emotional response from me on this site, it wouldn't be out of the question to assume that I'm being incredibly paranoid.
Don't tease, Elice. I haven't posted on GameFAQs since I suicided those alts away so you haven't had to deal with me. If you really want to accuse people of being me though, I can always come back for real and we can continue pretending to hate each other some more.
