yntbkshyfyn
A popular fanfic about Minecraft YouTubers, DreamWasTaken and GeorgeNotFound, titled "Heatwaves" by tbhyourlame on AO3, holds the popular line, "you need to be kissed, so hard, you forget your name." This sentence is then abbreviated down to "yntbkshyfyn"
It's always 'ily' and not 'yntbkshyfyn' 🙄
