Dayo, Dattebayo, dattebane, dattebasa, etc are all expressions to put more or less emphasis (more or less rudely) on what you just said. Here're a few examples below:"Dayo" is composed of "da" is the informal form of "desu" which means "is, are, or am" and "yo" which is a particle used for emphasis.Example: "It's true dayo." -> "It's true, it is!""Dattebayo" is composed of "da", "tte" is an informal version of the "to" particle used to emphasize what came before, "ba" is the contracted form of "ieba" the conditional form of the verb "to say", and "yo".Example: "It's true dattebayo." -> It's true, I'm telling you it is!"
