Twerking on Subway Tracks: Women Risk Lives to Perform Miley-Inspired Routine (VIDEO)

Two unidentified women risked their lives while twerking on the subway tracks in New York City just inches from a 600-volt rail.

The rebellious pair can be seen performing the rump-shaking dance craze in path of thundering trains as an onlooker films the disturbing scene. The footage, which was uploaded to social networking site YouTube on Monday, shows both women happily twerking away despite their risky surroundings.

"No face! No Face!" the women plead while shielding their faces from the camera.

The 13-second clip was forwarded to the NYPD, which is investigating the incident.

It is unclear where exactly the twerking occurred, however an MTA spokesman said it appears to be a station on the 8th Avenue line.

It does not appear as though anyone was injured during the incident.

While twerking supporters insist that the routine is nothing more than harmless fun, critics fear that the dangerous subway incident may inspire copycats.

Twerking, which is described a suggestive dance routine, has been popular on the hip hop scene for more than two decades.

Pop star Miley Cyrus was credited for introducing the dance craze to mainstream pop culture following her controversial MTV VMAs performance in August, according to E! News.

During that same month, the Oxford Dictionary added the word under the entry: "Twerk, verb."

"There are many theories about the origin of this word, and since it arose in oral use, we may never know the answer for sure," Oxford Dictionaries' Katherine Connor Martin said.

"We think the most likely theory is that it is an alteration of work, because that word has a history of being used in similar ways, with dancers being encouraged to `work it.' The `t' could be a result of blending with another word such as twist or twitch," she explained.
