The phrase comes from a 2015 clip attributed to Baldo and shared around the marathon event tagged MaratonaSGRB2015, where 'E lá vamos lá' works as a simple call to get going. As a short, easily recognised Portuguese catchphrase, it travelled through soundboards and short-form videos, where creators reuse it as a starter rather than as a quote needing context. Its appeal is practical: the wording is short, upbeat and instantly understood by Portuguese-speaking viewers, so it still opens challenges, streams and group videos without needing an explanation.
