Short answer:
“Boofing” is a crude slang term that usually means putting drugs or alcohol into the anus to get high, and in some contexts it can also mean sexual activity involving the butt.

What Is “Boofing” (Urban Dictionary Style)?

In online slang and Urban Dictionary–type usage, boofing has a few closely related meanings, all butt‑related and usually explicit.

Core meanings

People use “boofing” in three main ways:

  • Drug or alcohol through the anus
    • The most common modern meaning is inserting substances (like cocaine, pills, or alcohol) into the rectum to get a faster, stronger high.
* This is also called _plugging_ , _booty bumping_ , or _butt chugging_ when it’s alcohol.
  • Sexual activity involving the butt
    • Some Urban Dictionary entries and forum posts use “boofing” to mean anal sex, “butt‑fucking,” or other explicit sexual play involving the butt.
  • Crude sexual “game” or joke
    • One older slang definition describes “boofing” as thrusting your genitals in someone’s face while saying “boof,” framed as a rude joke or game.

Because Urban Dictionary crowdsources definitions, all of these can coexist, and context matters.

Why it became a “trending topic”

The word spiked in visibility during U.S. political drama when then–Supreme Court nominee Brett Kavanaugh was questioned about the term in his old yearbook. He claimed it meant flatulence, but many commentators pointed out that in common slang it was already associated with drugs via the anus or sexual acts. Since then, it pops up regularly in memes, Reddit threads, and rants about how gross the word sounds.

Health and risk notes (important)

Even though people sometimes joke about it, boofing drugs or alcohol is medically risky :

  • Very fast absorption can mean a much higher risk of overdose, especially with alcohol or strong drugs.
  • The rectal tissue can be easily irritated or torn, which can lead to pain, bleeding, and infection.

If you or someone you know is experimenting with drugs in any way, talking to a medical professional or a local harm‑reduction service is far safer than relying on internet “tips.”

Forum‑style recap

On forums and Urban Dictionary, “boofing” almost never means anything wholesome. It’s usually about putting substances in your butt to get high, or about explicit butt‑related sex jokes.

TL;DR: When people ask “what is boofing Urban Dictionary,” they’re usually asking about the slang for inserting drugs or alcohol into the anus for a stronger high, with some entries also using it as a crude term for anal sex or other butt‑focused sexual jokes.
