Everything related to wet and messy (or "wam"), be it ponies or Equestria Girls.

Keep in mind that this group is SFW since the subject matter itself is, and has been seen several times in the show. If you post anything in the forums about a less platonic interest in "wam", please mark the thread "NSFW". Otherwise, keep discussion of it clean. (Figuratively, if you're into the "messy" side )

That said, "wam" only refers to water, mud, slime, frosting, and other SFW substances you could expect to see in the show (including spit or sweat), so if they get wet or messy with anything NSFW it doesn't belong here unless it has substantial amounts of standard "wam" as well.
