someone who believes that a diet is good idea and yet they never lose weight. Hmmmmm what’s going on there hey? They are a dumb diet because they eat the things that are opposite of the diet.
When someone has done something atrocious due to negligence, they are either scum or they are dumb. They either knew what they were doing wasn’t right, and did it anyway, or they were too dumb to know what they were doing.
Guy1: You hear about the cop that killed that kid, thinking the kids corn dog was a machine gun?
Guy2: Are you going with scum Or Dumb here?
