There's a discussion of being "naughty" and wearing "special underwear."

A man and woman have sex, breasts are shown.

Another scene where a man and woman are having sex, no nudity shown.

Quite a lot of profanity and some light blasphemy.

A lot of smoking pot and drinking in the beginning.

A man and woman, while having sex, snort some cocaine.

There's a lot of running around and screaming as something (maybe aliens) chases the characters around the house. Also, the non-humans enjoy popping in front of windows and out from behind things at very opportune moments.R for sexual content, nudity, drug use and language throughout.
