ACR: Ambitious Card Routine/Ambitious Card Rising
a routine where the selected card goes in the center, and repeatedly comes to the top. Many books and dvds have been made on this subject, and is one of the most popular effects in magic, as it is visual, impromptu, and usually has a kicker ending, like the card appearing folded in the magicians mouth, or in a wallet or paperclip. for more info, i recommend reading "The Royal Road to Card magic" which has a section on this routine, and a large section of the double lift. For dvds, i suggest either Gregory Wilson's "Double Take", or Daryl's Ambitous Card DVD.
XCM
eXtreme Card Manipulation. Also known as flourishing, it is a skill and art form many people do now-a-days. It is a fairly new sport, only started about 10-15 years ago, and has become bigger, better and more popular these last few years. Most Popular flourishers you might hear about in these or other forums are:
Dan and Dave
De'vo
Allen Haglen
Chris Hestnes
Chris Kenner
The Cuso
Ineski
Kevin Ho
Bone Ho
Andrei
and many others who's names escape me.
Most flourishes are based off of Chris Kenner's "Sybil" or "the five faces of Sybil", which i believe were first published in his book "Totally Out of Control" which has recently been reprinted(great book). De'vo has a few dvd's that are out, which many say are amazing. The Flourishman, who's real name i cannot pronounce, has a book on flourishing, which many say is like a bible in XCM and flourishing. Dan and Dave's first dvd was The System, which has 26 card flourishes, which is what got them famous in the card community. Recently they have made a sequel 3 dvd set called the trilogy, which has a dvd on Flourishing as well. MAny youtubers post tutorials on they're own flourishing moves, which i recommend checking out.
Phew, that was quite a long rant, please excuse spelling mistakes, as i was a bit rushed.
Hope that helps
