Meaning

An online argument or flame war conducted through replies, abbreviation of レスバトル (reply battle).

レスバ refers to heated back-and-forth exchanges in online comment sections, forums, or social media replies. It carries a somewhat negative connotation, implying a pointless or aggressive argument rather than constructive debate. Being skilled at レスバ is sometimes praised ironically, but engaging in one is generally seen as a waste of time. The term originated on 2channel and spread to mainstream internet culture.
