Before having sex, a woman eats as much food, mostly colorful foods. Afterwords the woman deep throats her partners cock as far back as she possibly can until she gags and pukes all over his body. Thus creating a "cosmic sweater".
I'm really into fruity cereals and weird fetishes and shit, so I convinced my girlfriend to give me a cosmic sweater.

Before performing intercourse, the male consumes vast amounts of colorful breakfast cereal. Once intercourse is complete, the female punches the male in the stomach, making him vomit cereal all over her chest, creating a "cosmic sweater."

This is an neutral type of Matthew, they always wear a sweater no matter what temperature. They have an extreme liking to the feeling of cold, but does not care about heat at all. Most sweater wearing Matthews are very resilient to everything, and are very good with combat. About half of these Matthews know morse code and have hidden weapons on them everywhere they go. You should generally stay away or become A friend.
