ma'amuh
A woman who had a baby with your dad and then tried to claim you as her own. It’s like she thinks she’s your mom just because she had a baby with your dad.
She came to my graduation and said, "You’re my baby." That’s a ma’amuh.
She texted me, "You’re my baby, not your dad’s." That’s a ma’amuh.
She showed up at my job and said, "You’re still my baby." That’s a ma’amuh.
