A lie. If it was the truth, that would mean that statement was also a lie and that couldn't be right. Ты сказал(-а) that everything Ты tell me is a lie but the opposite of that is not necessarily that Ты tell me no lies. Some of the things Ты tell me can be lies, including that statement, just not all of them.
That remains to be seen. Obviously this Вопрос is an oxymoron. But since Ты сказал(-а) everything Ты сказал(-а) is a lie then you're lying but there is that off chance Ты could contradict your Назад announcement and actually tell the truth so therefore we really cannot conclude as to whether Ты did tell a truthful statement или a lie.
The above syllogism is invalid due to complete ignoring of the seven rules. If there are two doors, each with a talking door knocker one of which lies and one of which tells the truth and one of which leads to safety and one to certain doom. Which one leads to safety?
