Dirty soda – carbonated soda with cream and fruit puree or syrup mixed in – apparently hit social media radar with the reality show "The Secret Lives of Mormon Wives" some years ago. It became popular with LDS followers, who are not supposed to drink alcohol or "hot drinks" like coffee or tea. But apparently Olivia Rodrigo had something to do with the popularity, too, having had her photo with a drink from soda shop Swig in hand show up on TikTok.
