Spread
Prior to February 2021, the format did not attract attention from English-speaking users despite achieving significant spread in Spanish meme communities (example posts shown below, left and center). On March 27th, 2018, a dedicated Facebook group Memes de Boo Llorando was created. On December 23rd, 2020, Redditor Sad-Board posted one of the earlier viral English memes based on the image, gaining over 24,800 upvotes in three months (shown below, right).
On January 20th, 2021, Facebook page Paraguayita Ñañala posted a viral meme based on a photoshop in which Crying Boo is edited behind a driving wheel (shown below, left; author of the edit unknown). The post accumulated over 6,700 reactions and 13,00 shares in two months.
The meme received viral spread in the following month, with multiple users and meme pages reposting and remaking it. On February 17th, 2021, Twitter user @pyrorivarola reposted the meme, with the tweet gaining over 27,900 retweets and 197,100 likes in two weeks (shown below, right).
