Yeah, basically toilet humor. Granted, a lot of it is funny, but it's the non-family-friendly version (not that Apples to Apples is all that family-friendly once my family starts playing, and I'm sure that's the same with many others, but at least it has the potential to avoid offending most people's delicate sensibilities).

This is the juvenile dorm room version (which makes sense, as that's what they created it for in the first place).
