at the water's edge
Leaderless resistance is a technique in which small, independent groups or individuals challenge an established adversary. It can include actions from non-violent disruption to vandalism to various forms of direct action.
In leaderless resistance, a recognized leader or group gives generalized instructions or ideas of some sort and other groups or individuals — without having any direct contact with the apparent "leadership"—begin to act in such a way as to carry out the goals expressed by the "leadership."
Leaderless resistance has been used by a number of groups. For instance, it could be used by internet groups who might wish to suggest that a particular movement or website should be targeted in some way — but the suggestion could be phrased in such a way that those suggesting such a course of action would be able to claim plausible denial of any wrongdoing.
Sometimes someone does something that just pisses a lot of people off.
