When you spill your guts and reveal everything you've been feeling and holding inside you. This can be an angry outburst, but is usually a case of telling the object of your desire of how deep your affections go. After the emotional throw up, one usually feels a lot better as they got a weight off their chest.
To bring myself closure I sent my ex a message of emotional throwup and now I feel much better.
I Can't Fight This Feeling Anymorrrre!!!
