El/lo que faltaba para el duro

[ROBINDESBOIS]

Meaning that that's what we needed it. Any expressions in English?:D

"Just to cap it all!" (ironically)
"Just when things couldn't get any worse..."
"That's all we needed!
"That was the last drop"
"That was the straw that broke the camel's back"

Some of the above may give the idea... probably there are more, but I guess the Spanish comes from "duro" (a 5 pesetas coin), so I am not sure if English has some such expression with "money" or "coins"

The origin and explanation of the expression in Spanish can be seen here,

Or in en-gb, "Typical!"

(There's a good discussion of the use of this word in Watching the English by Kate Fox).

Great point, pjt33. :thumbsup:
I found the reference you mention, and it is very applicable!
