'Slackness' means being lazy or not working hard enough, and can be used to describe someone who is not motivated or productive. It is often used in a negative way to criticize someone's work ethic or performance. For example, if a student is not doing well in school because they are not studying enough, you can say that they are showing slackness in their studies. It is important to be aware of appropriate situations to use the word, as it can come across as rude or insulting if used inappropriately.
