When a person who is jokingly referred to as "immortal" in memes due to their great longevity and surprisingly good aging actually dies, causing mass hysteria and confusion.

When an immortality fail occurs, it spreads quicker than any other celebrity death. Typically, it takes less than an hour before everyone has heard the news.
The most recent immortality fail as of this post being written is Elizabeth II. With her death, Keith Richards is now the King of Immortals.

The mistake couples make when a partner sticks his penis or a lesbian uses a dildo or her fingers to penetrate the anus of a woman and then proceeds to stick the same appendage into the woman's vagina. They fail to realize that the woman's vagina will be contaminated with germs from the anus.
The lesbian porn scene was intense, but there was a front-to-back fail at the end of the scene. One of the women may need to do a heavy duty cleansing. dirty vagina, vaginal infection, unclean, wipe front to back, stinky gouch
