If your #fanfic summary starts off "All characters were bornded in 2008 instead" I'm not reading any further. Bornded? Really? I can't even...how do we get to bornded? Born is already the past tense! Okay, but if you didn't know that, I could see borned. I don't like it, but not everyone speaks English, and that's totally okay. But if you're using some kind of translation dictionary, wouldn't it give you the word "birth" and so then you'd write "birthed"? Birthed isn't my favourite, either, but it's fine. It's a real word. I've been sitting here for several minutes trying to figure out how anyone, anywhere, gets to "bornded". I would even accept "gived birth to", especially if your native language isn't English; it's a good try.
@jscholes LOL nope. They were trying to age up the characters so the teen author wouldn't have to do historical research about what things were like in the 1980's, and could just give them all cell phones and have them listening to real music, rather than whatever medieval chanting they used to do in 1988.
