"She ate a double-quarter pounder meal from McDonalds, 3 pieces of chicken from KFC, and some yogurt from TCBY....all in one sitting"
"Damn she THICKE, SKINNYFAT!!!!"
A sports team that looks very strong from a distance, but the closer and more carefully you look, the more you realize they are not very good, and are in fact, very beatable.
Also applicable to companies.
Jim: Man, you see how good New York looks, they are going to dominate the playoffs.
Ralph: Nah, they are so SkinnyFat. They are very top heavy, can't win close games, can't manufacture runs, have awful coaching, and they are not goodunder pressure. They only win blowouts. If you punch them in the face, they quickly wilt.
Jim: I hate SkinnyFat teams, I always bet against those teams, bruh.
