Tons of (comedic) sexual dialogue. This is because kids drink contaminated lemonade and it makes them poop.

S1, There is a CGI render image of a teen stroking an another teen's penis, this file is shown multiple times in the series. Although shown from far away. You can barely see it you have to squint to see it.

S1, There is a lot of hand drawn images of penises and Vaginas running throughout the series. Hard to see.

S1, A teen is shown making gestures of humping a toy horse, it's in a comical sense though. And you can not tell what he is doing.

Very funny high school humor throughout.

Damn,hell, aas , and one use of shit are used rarely throughout season 1 and 2.

One episode features a surprising amount of underage drinking and drug use at a party (a teenager is mentioned, not seen, to have crushed up Adderall with a spray-paint can).

Poop are shown a lot. Coming back in a lot of different scenes. This can be considered offensive and gross, and can frighten people. It's good to have that in mind while watching season 2

Viewers should keep in mind that this show is a satirical take on true crime shows. So it isn't meant to be taken seriously and meant more for humor.
