vertical gymnastics

Vertical gymnastics is the obscure way to describe pole dancing without sounding like a complete ho/stripper. Popular with professionals and prudes, it allows vertical gymnasts a way to describe their "sport" without being judged (ho/stripper) and is approved as a safe for work term.
Vertical gymnastics is a popular emerging sport all around the world.
