Now Rachel, please tell me i didn't use the phrase "bolt" inncorrectly at any stage of your visits... maybe it has been erased from my memory due to a severe pummelling to the back of the head!
it's ok jojo, you didn't offend my equine dictionary at any point. although are you sure that enigma wasn't bolting wildly with you when you had minor brake-loss in the field? Looked like she was in total blind panic to me

!!
I think I am an old codger at heart though, I don't mind the bouncies, I don't mind the enthusiastic, a bit of airs above the ground is fine... but you are not getting me sat on anything that has been described as bolting, absolutely not.
We all get brake loss - Tia is a very nice person who is very soft mouthed and generally polite - but the other day I went into our fast work field thinking I'd have gallop, forgetting that I didn't quite have the right tack on (cavesson noseband, no martingale and just a nathe straight bar snaffle) I said GO! she obliged, when I went to put the brakes on, her head was up and it took me a good 45 seconds to pull up when it's normally an instant reaction - it happens, I wasn't on the ball and I lost control of an enthusiastic horse. Definitely not bolting though.
KC, to me if you can circle, it isn't bolting, as the horse is still reacting to the riders aids, albeit choosing to ignore the direct stopping one. The horse isn't in blind panic and is aware of his surroundings.
If you want to use the word, then go ahead but two things,
a. you give other people the impression that your horse is dangerous (and that you are a fruitloop for riding it!) when it isn't actually the case... the mentality that someone would want to tag their horse with what is often credited as being the most dangerous vice seems bizarre to me
b. if and when you actually sit on horse which is running in blind panic with no awareness of outside world or rider on board, you have no dialogue left to describe it - you say 'it bolted' and your friends reply 'so? didn't nimby used to do that?'
also, and particularly pertinent in todays suing culture..., I think it is important that we are all aware that stating that a horse has a serious vice could be construed as admitting liability if something were to happen (eg if selling a horse and buyer told that horse has no vices, but an accident happens to them, and they subsequently find evidence of dialogue that horse known to bolt... then you were previously aware of vice and in some way responsible..) worst case scenario, but it would make me think twice about it.
