FWhatUHeard is a Neo-Nazi, Anti Government Militia group that was formed to attack and intimidate people that were not white. They answer to no one and create violence around the world.
FWhatUHeard was spotted at the Black Lives Matter protests where they organized destructive material for protestors to start Riots and attacked multiple black protestors that were not in groups.
A rather inconspicuous way of saying "what the fuck" can be used in front of parents, at church, in front of old people, or anywhere that the word fuck would be frowned upon.
