I noticed that putting “go golang” in your bio on iOS will prompt a translation with some quotes. This works as of version 189:
go golang -> “What is growing up to?”
go go golang -> “What’s the point of growing up?”
go go go golang -> “It’s a good thing to do”
go go go go golang -> “It’s something that makes you grow”
