Parkslash is slash fanfiction involving members of the band Linkin Park. Was originally just Mike/Chester, but has now branched off into several different pairings. Parkslash happens to be one of the most, if not the most, popular slash fanfiction based on music artists, so much so that it got it's own name. Most parkslash is made by illiterate twits who just want to make a sex story, but sometimes there are some decent ones out there.
