Problem 1721. Backslang, odds are you used it at some point in time...

So backslang is a language that can be used to communicate in an easy decode code, if people know the rules of decoding it. Well this backslang follows rules that are fairly customary. You take the first letter of a word and put it in the end, then add 'ay' on the end.
