someone that does something before they think about it. But sometimes realizes that it was a mistake and that they are thinking they are a dumbfuck that they did it. So a dumbfuck is someone that realizes that they are a dumbfuck for thinking that they are a dumbfuck. I'm a dumbfuck for making this so confusing!
