1.
The act of leaving a used condom in the anus of one's sexual partner (who received the anal sex) without him/her knowing the used condom has been left in the anus. Once the partner defecates the condom out to their surprise they have then found an Ass Cheerio.
After mediocre anal sex I left that bitch an Ass Cheerio to remember me by.
