A Zimbabwean street diss derived from the word 'clown'. Has become fairly global recently due to its cool-ness.
1.Used generally as a term of endearment, among friends.
2.Can also be used to describe real-life idiots when a swear word is just not appropriate : like when at dinner with your gran, or your
girlfriends parents.
Side note: Can be spelt a number of ways, depending on how gangster you feel at the time - clizza, kliza, or klizza.
I know this is confusing but it's sort of like the terms 'just now' or 'now now' that all Southern Africans
understand, but the rest of the world doesn't.
