A name given to, mainly females, for being excessively gooey, especially around the underarm area. They are known for having various house hold objects disappear in their goo. They will often avoid wearing bikinis but when they do it is not a pretty sight that you'll want to be around. Layers and layers of goo will pour out eventually consuming everything in sight.
