A ridiculously unneeded term for a zip up sweatshirt, basically a hoodie to everyone on earth except 5 people who use the word sweat jacket.
Quiz:
What color is your favorite hoodie?
Maria: I dont own one!
Hayley: Yes you do, it is blue, you wear it almost everyday.
Maria: No, thats a sweat jacket, what are you talking about?
Hayley: NO, WHAT ARE YOU TALKING ABOUT???
