When you are having sex with a girl on the top bunk of a bunk bed, and you fuck her so hard that all four of the wooden bed posts of the bed shatter at the exact same time and the bed crashes down on the person sleeping in the bottom bunk, killing him instantly, and you continue fucking the girl.
I feel so bad I performed a fucktality on my roommate last night, but it was worth it.

Dying while engaging in sexual intercourse.
Marissa took up weight lifting when, once again, she experienced a fucktality when a 300 pound customer died while on top of her during sex, and she had to call 911 not only to remove him to the coroners but to have the jaws of life called in to extract her.
