Yes, my trainer uses this term a lot during lessons, like when asking my mare to stretch down into the contact. She says to "make sure she's giving you an honest stretch and just not using it to get out of the contact". Which, of course, is something she does all the time! She will stretch down and I give her more rein to stretch down with and as soon as she realizes she has a good length, she will pop up, head high, and off the contact.
