Dumb Shit

The kind of shit you do on a daily basis that leads you to finding this definition in the first place. It usually involves an action that can be described as completely frivolous and fucking retarded, or to the common man, stupid shit. It can also be used to describe someone who is equally fucking retarded and needs confirmation that the party isn't starting at 6 AM when someone tells them it starts at 6:00. A better term to call someone in this case is "obtuse dunderfuck".

"Hey I'm gonna go out tonight and vandalize the school! Wanna come with me?"

"No fuckass, I'm not doing any dumb shit like that."
