Another way of spelling "morra di" or "mor di", "mammaen din", "mamman din"(this is what children often say;meaning something like "your mom", and "moren din".The last is the old fashioned way of spelling it,using masculine gender instead of feminine,since the Danish language, to which the norwegian was closely bound for 500 years, does not have femininum in it.
"Mora di er feit!" meaning "your mama is fat!"
