someone who is just an idiot and cute at the same time. A goofball who does silly things and doesn't care what people think about him or her. Is somewhat socially retarded yet extremely funny in the things he or she says/does.
Ben Stiller is a goon and Will Ferrell is a huge goon. Ashton Kutcher is a goon in That 70's Show only. But track star Tyler Anyan is the biggest goon of them all.
