Passing

[Jellybaby]

¿Cómo se dice..?


"It wasn't a big deal, I just said it in passing."

"No fue para tanto, lo dije de pasada."

It depends on what you're meaning by "in passing". The original sentence only makes sense to me if you used "in passing" meaning "parenthetically" -and not any other of its many meanings-. In that case the right translation points to "No es para tanto; fue sólo un comentario al margen".
