CYF 

Check your facts (CYF)

A term one would use when correcting a person and adding a slight insult to it, because clearly he or she is a complete idiot non-deserving to procreate

"Actually Tina, the biggest drug of the 80s was cocaine, not heroine. CYF"

CYFM

The most AMAZING place where you go to chill with teens who like to eat and pray. You will leave this place a changed person, connected to God.

God is good. All the time.
All the time. God is good.

Ian: You going to CYFM this weekend?
Father Fred: HECK YES!

Cyfucks 

(pl. n.) People who intentionally attempt to change words that usually end with "-ce" to "-cy" just because they think it "sounds good," often creating words that aren't even real. Common examples include: purposefully saying "persistency" in place of "persistence," "tolerancy" instead of "tolerance," "obediency" rather than "obedience," etc.

Dave: Holy shit! Are you alright, dude?
Jim: Yeah, I'm good. Just ran into a couple dumbass cyfucks on the way home...
Dave: Damn that's too bad, I can't stand those fucking guys.
