"Shut the Fuck Up"
To the extent of being universally known, consistently used online, both on multiplayer games and messege boards.

Practiced in anger or irritation, to get someone to remain quiet.

With or without "Bitch", "Woman" or any demeaning and vulgar slang to show pwnership.
Typically used by two groups;
Newbies defending themselves, or
Persons prejuidice against them.

Neither practice proper grammar or spelling.
