look up any word, like darude - sandstorm:

this is the lowest of low. people who are both dumb AND bad pretty much dont have anything left going for them. dumb and bad is intended to be a powerful insult used primarily in insulting any opponents in any matchup one may face in life. use it to flame your lesser opponents and a violent response is sure to follow

can also be a reference to negative situations (similarly to using a cuss)
"our team beat yours by 35 points, you're dumb and bad."

*girl trips and falls*
"wow, you're dumb and bad"

*you left your wallet at home, but you already ordered food at a restaurant*
"ugh, dumb and bad"
