geo 

An obese girl who is too big to be considered just another whale. Named for a body weight similar in size to a small car. This girl probably consumes ridiculous amount of alcohol to sustain her weight. A "geo" doesn't seem to care about her weight and does nothing in an attempt to reduce it. Often seen with a ridiculously huge male counterpart.

Did Kayla gain more weight? She is such a geo.

Look at that tool try to hit on that geo.

I went to school at uwp but that geo is the biggest I've seen.
