To remove by waxing or shaving. EX: I will manscape my legs by shaving them.
This all depends on the culture, country etc. We are all individuals but I would say that if not shaving, which can cause skin problems, most ppl trim it.
In general, men who are hairy look best maintaining a certain level of hairiness, otherwise it looks unnatural, so do not manscape excessively. Some chest and abdomen hair, as well as forearm and leg hair, should be left if you naturally have hair there. Use clippers to cut body hair super short (clippers will avoid ingrown hairs as well). If your hair is very dark, a razor might look a bit better once a week--but the risk of ingrown hairs is higher. Waxing is very painful but effective for a longer period of time.
