Ashawo is not the same as the Nigerian word "ashewo".
It's a minor difference, which is why people get it mixed up.. someone posted saying it's a Nigerian word - it's not.
ASHAWO is a word from the language Twi, from Ghana and simply means slut, prostitute, loose, easy. It can be used for a guy or girl, but is usually used for girls.
That girl is an ashawo, she has had sex with so many guys.
