maa yadi
A guy who hits on his mom or someone else's mom like she's the last piece of cake at a buffet.
My uncle called my dad a maa yadi because he asked my mom to go out with him.
She texted him, 'You're a maa yadi,' after he asked her to sneak out with him.
He got called a maa yadi in class because he told everyone his mom was his girlfriend.
