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.
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*
just as meaningless as your mom goes to college
originating from the insulting term 'your mother'
as heard in movie: Napoleon Dynamite(2004). said by character 'Kip'
Kid2: Uhm, you're mom goes to college so why are you fucking with ME?
*note from entry-writer: I'm a mom, I go to college, I love Napoleon Dynamite, and I had never 'til today heard the phrase used in conversation.
