"damn" is a very tricky word to translate as it is very context sensitive, so I'll give a few examples of meanings it could carry. 1.) It can be used simply to vent anger like saying "drat!" or "shucks" or "ugh!" expletives in English can almost all be used in this way, but it is considered rude. 2.) It can be used to express sexual desire or attraction. This is very prevalent in the ICE (Inner City English) dialect of American English. An example would be "Damn she lookin fine" 3.) It can be used to express surprise as such: "Oh hot damn! that scared me!" (also American English) 4.) It can be used to express disappointment: "Damn. I really wanted our team to win today, but we lost" 5.) It can be used as a filler word "damn, man. I honestly have no idea

Construction workers in large cities are notorious for offering "cat calls" like that to passing women. They might shout out something like "Hey Baby! Can I have your phone number?" .

I don't know what it could have meant in that context. "Damn!" is short for "damnation," which means "condemned to hell." In middle-ages Christian theology, after death souls are judged and are either sent to Heaven where they live with God in eternal happiness, or they are sent to Hell where they live with Satan and are tortured forever in burning brimstone (sulfur). "Damn!" or "Go to hell!" is the kind of bad language called "profanity," religious bad language. When said to a person it is impolite, disrespectful, angry, and hostile. But it isn't sexual or racist. In the U.S. it's not considered very bad language any more. The 1939 movie "Gone With The Wind" was a turning point. It was shocking at the time when Clark Gable said "Frankly, my dear, I don't give a damn."
