A Shame Tornado is the feeling of depression that results from a massive drinking excursion. Does not necessarily mean you did anything shameful per say but if you did you probably would not remember. Shame tornadoes are more prevalent when you blackout ( or Time Travel) for any period of time. The older you get the more at risk you are for one of these episodes. They tend to last 24-48 hours after the drinking episode but have in some cases been documented to last as long as 8 days.
