Step Mom 

Aka “Bonus Mom”

Marries a man with children and because she loves said man so much, she adopts his kids into her heart and puts up with a lot of backlash because of it such as BM hating her existence and forcing children to do the same. Step moms are saints but are often not allowed to make important decisions for the children or love them despite step mom’s love and adoration for said children.

Her step mom gives her hugs and tells her she loves her so much. What a lucky kid to have such a loving step mom!

Any woman in a relationship (usually marriage) with a man having one or more children from his last partnership. As far as getting along with dads new mate some step-kid's do and some step-kid's don't. Bottom line is that this woman wants to be with the guy so much that she is willing to step-up to the situation.

A group of young-adult's are having a discussion about their parent's and one says " You guy's who's folk's are still together are fuckin' lucky...my step-mom is a BYATCH, always acting like my mom and shit." Someone else says, " My step-mom is awesome, she don't make me do nuthin' and I ain't neva' seen my dad happier."

Step-mom 

A women who has chosen to love a man as well as his children. While never trying to take the birth mothers place, a step-mother acts as a friend and role model.

A step-mother chose to love another woman's children as her own yet walks on eggshells when it comes to parenting. Most commonly seen as a home wrecker by insecure birth mothers, a Step-mom had the same dreams and goals for the children as she would if they were her own.

"I wanted to buy my Step-mom a mother's day card but my real mom wouldn't let me"
