Smoked or grilled meat that is so hot, that it's like committing suicide, just by eating it.
I was so depressed, I committed Bar-B-Quicide, by eating the entire "Flaming Bunghole Ghost Pepper" sauced rib rack at Jack Auf's Meat Shack with a hot coffee to wash it down.
A perspective on life involving the increase of risks, reduction of safety protocols, and a lack of interest in protecting one's life. Combines the words quiet + suicide. Usually present in individuals that aren't desperate enough to actively seek death, but are unable to move forward in life. (Also Quie-cide)
Jimmy is committing quiecide when he drives over the speed limit with an ineffective helmet, he isn't seeking death, but doesn't fight to survive.
