Yo Mama's a Milf

Alright, listen up, you chucklehead. This joke is saying this person's mom is so hot, she deserves some 'special' attention. I know you don't get out much, probably still living in your parents' basement, but a 'milf' is a hot mom. The rest is just... well, you probably don't need to know, considering your social life is probably nonexistent. Based.
