Sweetcakes means: It means that the item is both sweet and nice. This is like receiving a lunch free of charge. It is usually used to show appreciation and as a way of saying thank you. It can be used verbally: Sweetcaking has the exact same meaning as chilling. It’s easy to take it all in. Etymology: Although it doesn’t make any sense to a native speaker, I find that my native Swedish friends influence the language. (in Community Dictionary, added by Elías Hernández)
