someone who is just stupid,
and doesn't even know what doornail means anway so isn't really insulted by the term anyway.

Open up a can of dumb-ass

the self-inflicting nature of opening your mouth and saying things that are way out of line and inappropriate in respect to your current locale or circumstances; can also be doing some seriously stupid shit for your age.

Open up a can of dumb-ass: We went to the job site to complete our mission, but then our hosts opened up a can of dumb-ass by making a bunch of sexists remarks in front of one of our female teammates. That’s when we left the site, not before telling them that we will come back when they can act a bit more professional.
