There are multiple shots of Jeff masturbating, his genitals are blurred.

Many gross sexual references throughout, Jeff has a porn tab open on his computer and we see a frame of sex (no genitals or breasts seen). In another episode, Jeff is seen with an erection showing through his underwear.

There is some gore, there is lots of blood, people are stabbed, shot, exploded and various other violent acts are shown in detail.

Words like "dick", "bitch", "ass" and "asshole" are said, "shit" is sometimes censored, "fuck" is completely censored.

Characters hit bongs.

There is a lot of violence in the series but most of, if not all of it, is done for comedic effect.
