Cook Your Ass Off is a new TV show on HLN. In the cigar world, long ashes is a term describing the long ash that holds on at the foot of a lit premium cigar, indicating that the cigar was made with long filler tobacco leaves. This is a good thing. The words long ashes are also used by cigar smokers as a greeting, or when saying goodbye (kind of like aloha). Combine cook your ass off with the long ash at the end of a smoking cigar and you get Smoke Your Ash Off.
