(adj.) a term used to describe a person. typically a person who is unattractive and mildly "magoo-looking"; "Beans" (aka Stephen AnthonyLawrence) from the Disney show "Evens Stevens" is an example of an individual who is goopy
Originally comes from the word "droopy" it means extremely attractive and good looking. Although droopy means tired, sad, and lazy, the change in the "dr" and "g" change its meaning completely.
Personal Note: Do not use this word unless you say it, understand its meaning, and believe that who you are saying it to is in fact goopy
