In one of the episodes, a character's girlfriend is an implied lingerie artist, and the character also implies he can touch various private parts of her body.
Goofball flirts and makes jokes at max.
In one episode a main character says he drank a glass of cum (the drinking is shown on screen), but it is later revealed it wasn't cum late into the episode. Another main character freaks out throughout the episode though.
During a quick break from the main story, a main ghost character (male) is seen making out with another ghost (female). He reaches off screen and a comical honking sound is heard, accompanied with the text "pussy honk", which implies he grabbed her vagina. She doesn't object, and it is implied that they had intercourse when the male ghost is seen with kiss marks all over his face and he smokes a cigarette. No nudity.
