Radical leftists plan to 'f*** s**t up' Friday at NYC's train terminals. Oh, and 'f*** the police,' they declare.

A radical leftist organization known as Decolonize This Place indicates it's planning a large-scale "action" Friday in New York City in order to "f*** s**t up" at the city's train terminals. They call it "F*** the Police 3," and it's a protest against fares and police presence on the transit system.

The group posted a video on Twitter announcing the planned uprising. The text preceding the clip reads, "The streets are ours. The trains our ours. The walls are ours. This moment is ours. How will you and your crew build and f*** s**t up for #FTP3 on #J31 (THIS FRIDAY)? Issa mothaf***in' movement."

Here's the clip posted by a different — and less potty-mouthed — Twitter user. (Content warning: But the group's video contains more than a few F-bombs): 

What is the group planning on doing?

The video shows a trio of masked, hooded individuals, and the voice of the speaker in the middle is muffled presumably to hide his identity. The speaker asks listeners to "think of the ways that you can move in affinity" with other protesters "and f*** s**t up on J31 all day long."

He also indicates that Decolonize This Place will announce "meet-up locations" on social media — not that such a plan will attract the attention of police who can show up there, too, and exchange pleasantries.

According to the group's rather colorful " FTP Operations Manual," Friday's activities include "mass turnstile hops all day," "campus walkouts," and a "bike block." It appears the activities will take place in Brooklyn.

It appears by "bike block" the group is referring to an action involving a mass of bike riders who literally take over the streets and impede the flow of traffic. In the below video, bike blockers are seen intimidating drivers — and appearing to mock police, who can do little against such a large number of riders:

Anything else?

To be fair, Decolonize This Place appears to support nonviolence, as it instructs participants to not bring weapons of any kind to events and to not get into confrontations with police.

The New York City Police Department on Thursday told TheBlaze it's "aware of the demonstration and will have an adequate police presence in place."
