maa lun
This is the worst thing you can say to someone. It means your mom’s butt is your favorite place. It’s also how you get someone to punch you.
My sister said 'maa lun' to my brother when he ate the last cookie.
I said 'maa lun' to my friend when he cheated on a test.
My dad said 'maa lun' to my mom when she left the house for three days.
