HMW Meaning in Chat or Text Messages Online

HMW is not an internet slang, but rather an acronym for the phrase "Haste makes waste." This phrase means that rushing to complete a task can result in mistakes or errors that ultimately waste time and effort. For example, if someone is in a hurry to finish a project and doesn't take the time to double-check their work, they may end up making mistakes that require them to redo the work, ultimately wasting more time than if they had taken their time in the first place.
