Trump presidency in his own words.
Defined for the MAGA followers: If you're irresponsible, you're careless about the consequences of your actions. You can't really rely on irresponsible people. Being irresponsible is the opposite of being responsible and careful — you do what you like and don't care what happens afterward. Forgetting to feed your dog for a week is irresponsible.
irresponsible means gutless, careless, heartless, senseless.
