Non-stop graphic language. Copious R-rated profanity. A hard R/18 (in the UK) show all the way. Equal opportunity humor of the most vicious kind.
Cinemax content advisory for this show: rated TV-MA-DLSV for graphic violence (GV), graphic language (GL) and adult content (AC). Sometimes there's nudity (N), and strong sexual content (SSC) instead of adult content (AC).
Not for kids, but of course this varies by episode. Hard R and 18 (in the UK), but sometimes moderate R-rated stuff and 15-level (in the UK) stuff in the more lighter episodes.
Crude humor.
