A Brousin is a connection between male friends that have a special bond. For example they are your brotha and feel like your cousin.

A cousin by blood, but a brotha in life. Your boy. Your life-long best friend.
"Damn kid, your cousin is a balla."
"Yeah he is! ... And he's my brousin. I known that kid my whole life -- he's like a little brother."

a misspelling of "browsing", as in just posted, doin ya thang, browsing through the women you see... lookin for a night, not a lifetime
"we be runnin' through these women by the thousands, ain't no relationships, just hittin it and quit and we be 'brousin'"

"and best believe when I come see you, I'z gon 'brous' on the way"

- from 11/5's classic track "Brousin'"

Us two are brothers , & them two are brothers. But us two to them two our BROusin. Because we're brothers and were cousin's.
Example:
A woman who conceived a child by one man & a child by another whom are cousin to each other would then call those children brousins. Because they are both brothers & and cousin's at the same time.
