Notation on the music for the violin says "pick slide." I have heard of it on guitar. How would you play it on a violin?
(cannot comment, new user) @Doktor Mayhem: Violin strings can be wound and, with the exception of most E-strings and pure gut strings, usually are. E.g. my favourite strings (GDA at least, the regular E string is too harsh on my violin), the Evah Pirazzi, are wound with Aluminium (A) and silver (G, D).
I would likely try and emulate a "pick slide" with the side of the bow, not the frog, but it is pretty silent. It would work amplified or as a whole section in an orchestra, though. There are modern-ish composers that require you to do something like this, I have come across it in my orchestra "career"* (though not very often, and I cannot remember the composer).
*"career" in the sense of time spent playing in groups, it is not my day job....
It should be read the same way as for a guitar - you rake a pick down the strings - depending on the music you may have time to grab a pick, or you may need to make do. The edge of the frog can make a pretty good corner for this, but it is very hard compared to a pick, so you need to hold the bow gently, otherwise it will give you more of a grind.
