people who have absoluteley no fucking clue what they are talking about and say a bunch of dumb shit in order to make themselves seem smarter

Shitting without having your smartphone with you.

A vague insult hinting at the target's mental inability. Since nearly all insults are used interchangeably as expressions of overblown fury designed to humiliate or provoke retaliation, the exact meanings of any and all insults (as well as their applicability) are completely irrelevant, although they commonly make jabs at either the subject's difficulty managing cogent thought processes or his sexual performance/orientation. The common suffixes "fuck" or "shit" are often appended in the form of a surrogate adjective denoting the seriousness of the offense. A "dumbshit" person is therefore more dumb than a merely "dumb" person because of the presence of the "shit" modifier. As such, all you idiots inventing and quibbling over precise definitions are wasting your time and mine. Worse still are the dumbshits giving thumbs up and down.

a person that is stupid, retarded, or just plain ignorant; a combination of a dumbass and a shithead; also known as an asshead

an olim camper (14-15 years old) who attend Crane Lake Camp second session 2006. They are stupid. Typically, they rip $10 bills, think skating rinks are heated, think Jimmy Hendrix is a tennis player, almost get hit by cars multiple times in a day. These are not people who you can trust to behave in public places.

Dumb shit is not necessarily an insult, it can also refer to illogical or irrational feats of greatness.

someone who is a really dumb peice of shit.
