Loose

[Calcoyote]

Probably one of my greatest fears would be to use a Spanish word and not know that it has a vulgar meaning.

"Flojo" has a a literal meaning of "loose".

Por ejemplo: Los zapatos me quedan demasiados flojos (The shoes are too big for me).

But I was looking at this word in the dictionary and stumbled onto an idiomatic usage that was very vular. Do I need to avoid using this word? Is there a different word that would be better?
