MSP

MSP - abbreviation for the Afrikaans statement "Ma Se Poes" (Mother's Vagina). Can be used jokingly or when a person really is a MSP. Could either be used to insult the person’s mother, or the person themselves.
More commonly used by Afrikaans people, but will often be used in English sentences. This phrase is very popular among the Cape-coloureds (but they often use the whole phrase instead of the abbreviation).

“What’s up you MSP?”
or
“Hey, you’re a real MSP”
or
“Where can I find a condom now?”
“In your MSP!”
