It's by default a slang word mainly used among French-Canadian living in the province of Quebec to define all sloppy, dirty, oily, smelly and poor black Afro Canadian. Boogaloo usually drives very dirty, rusty and shitty color foreign cars such as rown or beige old Nissan or purple Toyota's. What we do call "A piece of shit car". They will not care when changing lanes or don't care if they hit you
