What's the difference between a dry man and an otaku?

Dry man: That is, a dry man who likes mushrooms and scallops. A dry man is a young man who has given up love. He always says, "This is the easiest way." Almost all of them sleep at home during the holidays, wear high school sports clothes, recline at home and drink beer and watch baseball broadcasts, DVDs and other otaku: these people who stay indoors every day and indulge in playing computer games, chatting online, soaking in forums, watching cartoons and watching TV dramas can be called otaku. People who go home from work and are addicted to something (even if it has nothing to do with the computer network) and rarely socialize will also be called "otaku".
