Fucjk is a common word used among people who often misspell the word 'fuck' out of anger. Other's tend to hide their anger using either: fawk, feck, fluck, or fluke; which is common among the internets.
"Chris was trolling the forums one day, replying to an insult. Little did he know that he spelled fucjk instead of the word he previously intended."
