"Your grandma ain't built the same as my grandma, your grandma ain't built right," Gates taunted.

"That's right, n*gga, motherf*cka knows," said grandma

"My Grandma put that hand on your p*ssy a$$ grandma," Gates continued.

"Pur that sh!t on them quick," the senior Gates added with a laugh.

Is your grandma worried?
