A rim job, also called rimming or anilingus, is oral stimulation of the anus using the mouth, lips, or tongue. It can be a part of foreplay or a complete act on its own, given and received by consenting adults of any gender or orientation. The term is casual slang, while anilingus is the clinical name used in health and research contexts for the same act.
Where the Term Rim Job Comes From
The exact origin of the phrase is not documented. The most likely explanation is the ordinary word "rim," meaning an edge, applied to the edge of the anal opening, with "job" added the same way it is in other sex slang. Today it is widely understood as informal shorthand for anilingus.
How Rim Job Is Used
In everyday conversation, this term almost always refers to the act itself rather than to one specific technique. Related slang for the same activity includes "rimming," "eating ass," and, less commonly, "tossing the salad." These words appear in casual conversation, in adult media, and in discussions of oral-anal contact between partners. Whatever term is used, the activity described is the same: oral stimulation of the anus, usually as one part of a broader sexual encounter rather than the entire encounter itself.
Rim Job Safety and Health Considerations
Like any activity involving oral-anal contact, rimming carries real health considerations worth understanding accurately. The main risks are hepatitis A and intestinal parasites or bacteria, such as E. coli, which can pass from the anus to the mouth even when the skin looks clean. Moving from the anus to the vagina or mouth of another partner without washing or changing barriers can spread the same bacteria. Some sexually transmitted infections, including gonorrhea, syphilis, and herpes, can also spread through oral-anal contact. HIV transmission specifically through this act is considered very low and is not a primary concern here, in contrast to anal or vaginal intercourse.
Using a dental dam, or a condom cut open into a flat sheet, as a barrier between mouth and anus meaningfully lowers these risks, as does washing the area beforehand. Anyone who engages in this activity regularly may also want to ask a doctor about hepatitis A and B vaccination. As with any sexual activity, ongoing consent and a quick check-in about comfort and boundaries help make the experience safer and more enjoyable for everyone involved.

Rim Job Meaning FAQ
Is a rim job safe?
It can be done more safely, though it is not risk-free. The main concerns are hepatitis A and intestinal bacteria or parasites, along with some STIs that can spread through oral-anal contact. HIV risk from rimming alone is very low.
Do you need a dental dam for it?
A dental dam, or an improvised latex barrier such as a cut-open condom, is the most reliable way to reduce disease transmission during oral-anal contact. It is worth using with new or non-monogamous partners, or whenever either partner wants extra reassurance.
What is another name for this act?
The clinical term is anilingus. Common slang alternatives include rimming, eating ass, and, less often, tossing the salad.
Is rimming the same thing as anilingus?
Yes. Rimming is informal slang, while anilingus is the clinical term used in medical and research settings. Both describe the same act of oral stimulation of the anus.
Why do people enjoy giving or receiving a rim job?
The anus has many sensitive nerve endings, so oral stimulation there can feel intensely pleasurable for the receiving partner. For many people, this kind of intimacy also builds trust and closeness, since it involves a level of vulnerability that depends on clear consent and comfort.
