When you find semen recently ejaculated on your belongings and it is unknown who did it or where it came from.
A student arrives at his dorm with a few of his friends after classes. He drops his things on the floor and sees his computer chair covered in semen. He knows he didn't masturbate that morning, so he looks at his friends.

"Who the fuck did this?!"
None of them answered.
"It's a cumspiracy." one of them whispered.
