An insult in Lozi language of Western Zambia meaning "your feaces or your feacal matter".
e.g give me my money you've been owing for the past 2 years, masipa ya hao!
Equivalent to "your feaces" in English...it's a popular Lozi insult which other tribes in Zambia tend to know without really knowing exactly what it means.
Joe: masipa ya hao! You stepped on my white sneakers!
Brian: oh sorry bro but you didn't have to insult me like that...it hasn't gotten to that.
