Father. Mostly used by single welfare mother in inner cities or married women that never came across the word husband in the dictionary.
Anna: My baby daddy is coming today
Bill: Please, never use that term, ever. It makes you sound like a poorly schooled moron. And then you probably wonder why 'the baby daddy' was beating you on a daily basis.
A dude who impregnated you who sits around bashing you all day for his faults. Fails to show or say what he has done to make you this way. Still holds onto grudges and finds the most ignorant amature ways to upset you. Every chance he gets he try to belittle you and slander your name. Hold onto feelings that need to be released.
Girl my petty baby daddy over here lying about what really happened trying to make himself look good.
