fuckposter 

Someone who needlessly adds profanity to public posts on social media solely to appear "edgy," cool, or more intelligent. They will typically add unnecessary "fucks" when posting in praise of something (e.g. some movie, show or band is fucking amazing) when the complimentary adjective is sufficient. The fuckposter will often also subscribe to the theory that intelligent people use more profanity in conversation, while not grasping that this only applies to spontaneous verbal communication and not to planned written posts and emails.

"Man, that dude never misses a chance to shoehorn a "fuck" or "shit" into every post. He's a real fuckposter."

Fuckster's Law

When you Google a question the first result is always a forum post where the first reply is some fuckster saying "Google it"

"I just googled this question, and the first result was just this fuckster telling me to google it."
"Dude, that's Fuckster's Law in action!"
