"Besides, baby's daddy is wrong. It`s Baby daddy. No "`s". Just Baby Daddy."
Not everyone lives in Crack`ho-Land or in Wannabe-Gangsta-Ville. "Baby-daddy" is NOT correct. It is a colloquial contraction from "baby`s daddy" perpetrated by those too lazy to speak correctly or those who are trying to convince everyone around them that they`re "ghetto."
