I really don't pay any attention to terminology for the sports that I have played(Bowling, and now Disc golf)... There are many terms that I hear out on the course--that I have no idea of what they mean exactly... Can I get a little help???
And yes I could look them all up, but isn't that what a message board is for???
1)overstable
2)understable
3)upshot
4)flip shots
5)flex shots
6)turnover throw
7)pulling the disc
Thank you in advance(IF THERE IS ANY HELP!!!) 
1) Overstable - the quick and simple definition is for a RHBH (right handed back handed) thrower, the disc will fade to the left at the end of the flight, but according to Dave Feldberg, an overstable disc just wants to crash to the ground as soon as possible.
2) Understable - almost the exact opposite of overstable, for a RHBH thrower, the disc has a tendency to turn to the right during the early part of the flight, and again according to Feldberg, an understable disc wants to avoid the ground for as long as possible.
3) Upshot - an upshot is generally an approach shot when you're intent is to put it in or around the putting circle (30 foot circle around the basket).
4) Flip shots - a flip shot example (but not the only example) is when you take a disc, throw it on a hyzer line, and because of the wear of the disc, the stability of it, or just the amount of power put into the throw, the disc during the early part of the flight (the turn) comes out of the hyzer line and straightens out.
5) Flex shots - a flex shot is also known as an s-curve or s-shot, where you generally take an overstable disc, throw it with an anhyzer line, and when the disc starts to slow down, because of the overstability of the disc, the disc starts to fade back to the left, causing it to have an 's' shaped route.
6) Turnover throw - when you throw a disc that is generally understable, and throughout most of the flight, the disc turns to the right for a RHBH thrower, without a harsh fade to the left at the end of the flight. Generally a shot used when a RHBH is throwing on a dogleg right hole.
7) Pulling the disc - this is when a RHBH thrower accidentally holds onto the disc too long, puts too much into the the throw, or applies to much OAT (off-axis-torque) and causes the disc to shank off to the right or turns over to the right when not intended.
This are my understandings of the definitions, but I'm sure there might be a disagreement or two, but for the most part, I think this will give you a good idea. Hope this helps!
