Probably derived from the word syphilis, which is a venereal disease. Was probably first used in the military to describe anything not clean enough, such as a soldier whose hygiene was not up to scratch, or barracks which was not on inspection standard.
A word originating in South Africa. Mostly used by young people to describe something that is repulsing, disgusting, gross, revolting, etc.

Siff
In Italian it means very STRONG girl who can also be very soft. It's rumored that Siffs are secretly forestspirits since they often live in the middle of nowhere and are surrounded by animals.
