fucksayer 

A person who uses the word 'fuck' to excess, often in the interest of sounding more intense.

You: "I can tell you're really serious about the topic of conversation, and that impresses me. You're a total fucksayer and obviously a badass."

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!"

Fuckslayer 

The most badass musical instrument in existence

Harry withdrew his guitar, Fuckslayer, from a dimension where all screamed for naught.

Wrought from the silver heart of heaven's false promise, laced with vessels that pulsed with angel's menstrual blood, hewn from the horns of Satan's generals, it laughed as it was set loose, a laugh that only Harry could hear, but no one could share.

"Did you see Darius chillin' wit Chinika the other day?"
"Yeah, bruh, that's fucked up. Chinika is Darrell's girl."
"See, bruh, that's the kinda fuckassery I can't stand!"
