That era of the late twentieth century that lasted from about 1986 to about 1997. The childhood of Generation Y and the young adult/teen hood of Generation X.

Named of course, after the Nintendo character Mario, who, with his love of pizza, and goofiness, in my opinion really defined that era from the late 1980s to the mid 1990s.

Good times. Just prior to the Mario Days was the Atari Age (1977-1985) and just after was the cultural Dotcom era (1997-2005). Today, and since about 2006, we are living in the Emo Age.
'Remember what it was like, back in the Mario Days? We'd play Nintendo, eat pizza, and look at the moon. The Internet was a rumor then, time ran a little bit slower.'

'Yeah man, I miss those days.'
