A father figure to a child that is not married to the mother.

A father figure that stepped-up to the plate.
This is my mom and step-up dad, they take care of me.

Get the step-up dad mug.
A woman who quite literally is a motherfucker, who is more manly than a father. Typically owns more tools, alcohol, and firearms than most men. Has the fighting capabilities to whoop yo ass. She also possess female capabilities such as cooking, cleaning, and household renovations.
It’s a woman, it’s a man…it’s a STEP-MOM-DAD!!

A cowardice loser who your mom made the mistake of sleeping with after divorcing your equally terrible biological father. Your mom will slowly begin to care about your step-dad more than she cares about you and will completely ignore, or even take his side when he decides to project his own insecurities onto you by relentlessly bullying and trying to make you feel bad about yourself for years. Your entire family will see your step-dad as a good guy and the perfect substitute for your abusive biological father, when little do they know, he causes you the same amount of emotional distress that your biological father used to. Your step-dad will also make you feel like your problems simply don't exist and will call you an attention whore if you even dare to mention or express any type of mental health problems you have in front of him. And the worst part is that you will have to deal with this feeble excuse for a human being until you are old enough and financially stable enough to live on your own.
I hope my mother divorces my step-dad someday

Dad Joke to offensive to tell your own children, but if it’s someone else’s you don’t care.
I probably shouldn’t tell you that joke. It’s more of a step dad joke.
