This phrase, related in part to the "blat" (see "blat"), describes the logical aftermath of drinking too much Blatz beer. If one drinks far too much Blatz, the next morning's activities are dominated by the "Blatz splatz" in which bodily fluids are emitted from various orifices in a semi-involuntary spasm. This term is obviously only used in those areas of the country where "Blatz" beer is found. For additional information see "hershey squirts" and "the shits".
Man, Frank brought a few cases of Blatz to the stag party. Damn, the next day let me tell you, I had the Blatz splatz big time!
