Men commuting on New York City subways have reportedly been taking part in a new perverted trend targeted towards women.

The disturbing trend, which involves a guy taking a picture of his private parts and sending it to nearby parties via the iPhone AirDrop tool, has left some unlucky ladies feeling violated, repulsed and utterly confused.

Britta Carlson, 28, told the New York Post she received an unusual request from an unknown contact July 27 while riding aboard the 6 train en route to a concert.

The disturbing trend involves a guy taking a picture of his private parts and sending it to nearby parties via the iPhone AirDrop tool

The AirDrop tool was first released on the IOS 7 update in July 2011

When Carlson accepted the request to view the message, she was petrified.

'It was just a huge close-up picture of a disgusting penis,' Carlson recalled. 'It really felt like someone had actually just flashed me.'

Carlson said she was able to receive the unsolicited photo from the stranger because the tool was customized to 'Everyone,' rather than her saved contacts only.

'It never even crossed my mind that someone may use it to send stuff like that.'

The AirDrop tool, which first released in July 2011 on the IOS 7 update, allows users to easily transfer files and images to people in their vicinity without occupying storage space.

iPhone users have the option to turn the settings off or to 'Contacts Only'

'Just tap Share, then select the person you want to share with,' Apple's website described the convenient tool.

'AirDrop does the rest using Wi-Fi and Bluetooth. No setup required. And transfers are encrypted, so what you share is highly secure.'

iPhone users are able to block messages by turning the tool to 'Receiving Off,' however; many are not aware of the different options.

In another creepy incident, 35-year-old Frankie Navisch revealed she was recently departing a train at Penn Station when an invitation titled 'Eduardo's picture' popped up on her mobile device.

Navisch said she 'wanted to punch him in the mouth for carelessly buckshotting genitalia' to a random phone.

Sex addiction therapist Brad Salzman said before iPhones, people had to go out into public to expose their private parts

Sex addiction therapist Brad Salzman told the newspaper these incidents have become more common in the constant-evolving digitalized world.

'In the past, flashers would have to go out in public,' Salzman said.

In a similar episode that went viral last last month, college student Madi Kohn, 20, received numerous unwanted penis pictures via the dating app, Tinder, which inspired her to get revenge.

In her Tinder bio, Kohn warned in an update: 'If you send me dick pics I will send them to your mom.'

One reckless guy challenged her, and Kohn searched his social media profiles where she located his mom and sent the risqué image.
