The phrase became famous in Brazil in 2010 after a figure presented as ET Bilu appeared in television interviews claiming to bring a message from extraterrestrials. His repeated advice, busquem conhecimento, was treated as both mysterious and unintentionally funny, and short clips spread quickly across Brazilian internet forums and video sites. The line outlived the original reports and became a national meme catchphrase, reused whenever someone acts like a prophet, shares a strange theory, or gives advice that is meant to sound far deeper than it really is.
