It’s a combination of an online news aggregation site, rating site, and online forums where people can spout their opinions, for better or for worse. Personally, I can say that I’m addicted to porn Reddits (certainly NSFW gifs!). Explain yourself!NSFW Reddit is an amazing site on the web with a long history that is not specifically adult oriented per se, but it does have a lot of adult content on it.
WTF is a Reddit, PornDude? It sounds like some animal.
