Yo Mama is a reference to yo mama jokes meaning when you say yo mama that means you think their mom is ugly fat or stupid

Your baby mama is when you accidentally get a woman pregnant-- oopsie daisy-- but you two aren't together. If a pregnancy is the result of a one-night-stand, she's your baby mama and you are her baby daddy. Sometimes you two can agree to raise the child as single parents, but in cases like How I Met Your Mother (Barney's mom), the baby mama will raise the kid on her own.
