Una noche para cortar las venas

[poli]

What does this mean?

[Rusty]

cortarse las venas = to cut/slash/slit one's wrists

para cortarse las venas
I believe this phrase is used to describe something depressing, like a depressingly lonely night. Songs that depress you, like a melancholy bachata, can be described as canciones para cortarse las venas.

There may also be a "good" slitting of your wrists. That would be akin to saying "this stuff will kill you," when we mean that something's very good.

[poli]

Yes Rusty. That's what confused me. The phrase described something positive. I guess it's like "to die for".

[ROBINDESBOIS]

No, it means that you don´t want that terrible night to happen again. ( It was so bad)

This option is exactly how Spanish people use it.

This other option, I guess is how Spanish people in the US have added its use. And it may be spreading to other places too by youngsters.

Agree with Chileno and Robin
So heard, the sentence is bad, The night was a nightmare, and I wanted to cut my veins.
Other usage I don't know. perhspas it's something like " it was so a good night that I wanted to die with that last memory" but it's not the normal spanish usage, must be youngsters as Chileno/Rusty thinks.
