“Ferg” may be used as a more appropriate and less profane way to speak/say the word “fuck.” In other contexts, you may say “ferging” or “ferged.” (Not in any way to be confused with or associated with the song “Fergalicious.”)
Exhibit A:
Man 1: Throws Man 2’s bike out of a window.
Man 2: “Dude, what the ferg man!!?”
Exhibit B:
Man: “Dude, I ferging hate you!”
Exhibit C:
Man: “Oh boy, you’ve ferged up now.”

Get the Fergmug. Reaming a dude from behind (doggy-style) and then rimming his asshole with your finger with which you run it (fecal matter and all) under his nose as to make a moustache with. Similar to the Dirty Sanchez, except strictly male related.
