A phrase used by the elderly generation, most likely to mock or make fun of today's younger generation. ""Totes" is a shortened version of "totally" that is often used in text or commenting on social media. "Mc goats" came in as a form of mockery because it rhymes with "totes", and the spelling was changed to "toats" so it looks like goats a well.
My elderly grandfather finally got a cellphone and sent me a text message saying "This is toats mc goats cool."
