The phrase is Portuguese, with respeite meaning respect and lisho sounding like a drawn-out, misspelled version of lixo, meaning trash. The exact recording source is not widely documented, so the clip circulates mainly as a standalone reaction sound on soundboards and in chats. Its short length and single clear line make it easy to repost, download and drop into unrelated conversations. Brazilian and Portuguese-speaking users in particular share it as a joking comeback, and that simple, repeatable use has kept it alive beyond any original context.
