Rusty Trombone

The term "rusty trombone" refers to a sexual act that combines manual intercourse with analingus at the same time. Its term comes from the way one person seems to utilize the other's body as a trombone, stroking the penis with one hand while placing their mouth to the anus.

When Detroit radio team Deminski & Doyle discussed urban legend sex acts in 2003, it was the first time the word was used in public. It became well-known when it appeared in several movies in 2005, such as The Aristocrats, The 40-Year-Old Virgin, and Tenacious D in the Pick of Destiny.

Another name for a rusty trombone is a dirty or a rusty trombone.
