It's a replacement for the word "f*ck" or "Hell." Generally used by the people of MLIA, often describing whatever OP did this time.
Mobile- "...the Circafan?"

KWinchester- "It's ok Mobs, just take deep breathes."

EugeenieWeenie- "I have to pee."

Everyone- "Why the Circafan would you tell us that?"
