Most people, even musicians have trouble keeping up with the slang in the industry. So there is a lot of misinformation out there. And there are so many hobbyist types who guess like they know what the real answer is that there is a lot of misinformation out there. I thought I knew intuitively what some terms meant but later found out that in many cases I was as rookie as most of the masses.
I’ve heard so many different definitions for music slang. There are resources that define words that are slang. Chops, for example is defined in the non-definitive by remarkable Urban Dictionary site:
Ability to play on any instrument (guitar, drums, brass, etc.). Used for guitar and drums because of the chopping motion made by the hand, and used for wind instruments because chops is also slang for one’s mouth.
On drums: He played the beat so fast. . . he has amazing chops.
On guitar: Did you hear that solo? He’s got wicked chops!
On brass: You have to have some chops to hit a double G.
