The action of punching someone in the face when they come within 6' / 2m of you during the COVID-19 pandemic.
Joe: That guy is getting close
Chris: Don't worry, I'll take care of him with a little social fistancing.

The act of, in the year 2020, using all forms of media to angrily force something false, (an idea, policy, false election results, covid-19 misinformation) upon an otherwise informed public.
The Trump administration by way of base, has attempted to feed a continual line of bullshit up the rest of the world's ass through the practice of social fistancing.
