D.F.F.C.
Drug free for Christ. A holy vow to stay clean, no drugs or alcohol, just so God won’t make you do push-ups in church.
I’m D. F. F. C. and I will not eat the holy wafers. They’re just carbs.
I’m D. F. F. C. but I took a hit from the bong. I’m now D. F. F. C. and slightly high.
I made a D. F. F. C. promise, but I had a beer. Now I’m D. F. F. C. with a hangover.
