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."

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.

The female equivalent to shirt-cocking, where a woman wears only a sweater, often post-coitus, but nothing else. Unlike "shirt-muffing" where the female subject may intend to dress provocatively in order arouse men, a sweater-muffing individual hopes no one will see her and uses only a sweater usually because it is easier than putting on normal clothes or because she is cold.
Sweater-muffing is common when performing quick rudimentary tasks after intercourse such as running to the kitchen to get some juice or checking one's email.
