No, it's not something sexual. Boneland.com is a site with tons of mini games and cartoons that are just absolutely hilarious. I've been there a billion times, and laugh so hard I can't breathe every time. If you go I recommend Alcohol & Ammo, Bats & Balls, Crash Test Dumbass Overkill, and the Judge Hellfire videos. Bumblestick is also a riot. So go and laugh yourself so hard you need an inhaler.
I should probably mention that it can get fairly vulgar in spots, so if that bothers you, you may not want to go.
