Originating from the lackadaisy slam, "Your mom." Made crazily
popular by
Kip in Napoleon Dynamite (2004.)
This term is used basically whenever it is wanted, even if it is completely random or irrevelant to the subject at hand.
That's okay. At least my mom doesnt go to
college. She's a housewife.
Ann-
Shut up Bob! You
suck!
Bob- Your mom goes to
college!
Ann- That is so last year.
Bob- Your MOM is so last year. HAHAHAHAHA!
Ann- *sighs and walks off*
