In the 90s they put random English phrases instead of translating.

Bad example. The original line was already about shorts. It also became a meme in the series and lots of later episodes have some guy being enthusiastic about shorts around the begining of the game.

It’s true this sounds a bit more random in English than Japanese, but it was an attempt at translating it.
