A sense of longing frustration brought on by something so attractive, pleasing, or ideal that a person can't deal with it. A frightening paradox of pleasure that's so good it must be avoided.
To contrast with negative frustration-based rage types, blissrages are occasionally welcomed or sought out by the rager depending on the situation. They are just as often, however, completely avoided by persons who don't want to risk losing composure in certain circumstances.
Celebrity attractiveness, delicious foods, music, and puzzle solutions are common causes.
Flo from the Progressive commercials has such a hot voice that I can't watch TV because I'll blissrage hard if she comes on. I nearly crushed my remote in sexual anger the last time she said, "happens to me all the time!"
