One of the main themes of the movie involves one of the main protagonists is feeling he's loosing his sexual feelings to his girlfriend, which leaves her girlfriend concerned. They can be seen preparing having sex. We see their bottom underwear but no visible parts are shown.

Then one of the main protagonists tries to use all kinds of things to make sure he will get his sexual feelings again. One of them shows a brief reference to BDSM by slapping the mans butt.

Lots of sexual jokes are used.

A man tells how big a dogs penis is.

Not much really, there aren't any blood or gores but a few personal fights might occur.

A man throws his newly bought liquor to the ground after becoming angry and swears.

A group of men hunts down one of the protagonists after he lost one of their dogs.

Some casual Swedish language swears can appear. Also strong English swears appears more later of the movie such as "f**k", "sh*t".

A few references but nothing big.

Overall this movie isn't necessarily scary or frightening but some might find the fight scenes a little intense.
