What does dirtbag mean?
Dirtbag is an informal English noun with two strikingly different uses. Its dominant meaning is pejorative: a contemptible, dishonest, or thoroughly unpleasant person, roughly equivalent to 'scumbag' or 'lowlife'. In this sense it carries real sting and is best reserved for casual speech, as in 'he treated her terribly — what a dirtbag.' More surprisingly, within climbing, skiing, and other outdoor communities, a 'dirtbag' is someone who deliberately lives frugally — often sleeping in cars or tents — in order to spend maximum time pursuing their sport. Here the word is affectionate, even admiring, and frequently self-applied. The term combines 'dirt' with 'bag', evoking both moral filth and, in its positive sense, a rough-and-ready lifestyle. This rare ability of a single insult to signal either contempt or camaraderie makes 'dirtbag' a vivid example of how slang meanings diverge across communities.
An unpleasant, contemptible, or morally disreputable person.
"Nobody wanted to work with him once they realized what a dirtbag he was."
Informal and mildly offensive; chiefly North American.
In climbing and outdoor slang, a person who embraces an austere, low-budget lifestyle in order to pursue their sport full-time.
"He spent two summers as a Yosemite dirtbag, living out of a station wagon."
Often used affectionately or self-descriptively within the community.
Regular plural; used identically in both senses.
"The campsite was full of dirtbags heading to the valley for the season."
The same insult used for a cheating boyfriend is worn as a badge of honor by rock climbers living out of their vans.

Etymology of dirtbag
Dirtbag was formed in English from the noun 'dirt' plus 'bag', following the same pattern as older compounds like 'scumbag'. It emerged in twentieth-century American slang as a general insult for a worthless or contemptible person. By the late twentieth century, climbers and other outdoor athletes had reclaimed the term, using it proudly for those who sacrificed material comfort for their passion. Its components are native Germanic English words, so it has no cognates in Latin or Greek.
How dirtbag is actually used
Strongly informal and mildly vulgar in its pejorative sense; avoid in formal writing. In climbing, skiing, and van-life communities, 'dirtbag' is often self-applied with pride rather than offense. The insult sense is especially common in American English.
Easily confused with dirtbag
Both are insults for a contemptible person, but 'dirtbag' can also affectionately describe a scruffy, dedicated outdoor enthusiast, while 'scumbag' has no such positive sense.
