A dumbus is a person who is simply very dumb and idiotic

Almost the same as a dimbus but worse
Person #1 Hey look at that hole in the pavement!

Person #2 I'd be careful around that
Person #1 But it looks cooollll we should go in it
Person #2 No you dumbus shut up and keep walking

Person #1 Ugh fine you stick in the mud
