A creature who cannot be trusted to even take care of himself properly. Most of the time dumdshits are closey related to fucktards, fuckboys, asshats, droolies, pond scums, fuckwits, manwhores, bride jumpers and all other low lyfes who think they can just skate through life hurting anyone and everyone so long as they get what they want in that very moment. Dumbshits rarely are respected and are seen as creatures of great algae eating abilities. Dumbshits think they know what's best when in fact just tend to fuck things up for society as a whole. Dumbshits can rarely make a good decision when it comes to being a decent creature. These sort of creatures usually feed off the bottom of the pond. Most of the time they are known for their conniving fuckboy like attributes that include but are not limited to: dishonesty, ignorance, manipulative personality.
