DaBears were down by 21 with under 2 minutes to go but my CFS (Chicago Fan Syndrome) knew they would somehow pull off the win.

cf

Short for casual fapping.

It's like foreplay for masturbation. Also done out of boredom sometimes.

cf means casually stroking one's dick without any real intention of reaching climax (yet).

"Yo, what are you doing?"
"I'm bore, so just some cf."

Lollygagging CFS style

a person who dawdles or fools around and drags
things out, usually from California

RTA aka "Lollygagging CFS style" has a bad habit of lollygagging around instead of getting things done in a timely manner.
"Ron, quit lollygagging!!!"
