Not too quickly or abrupt like a scratch, but when it's done at a linear speed at something like a tenth of a second both ways, further the record is brought to where it would have been had this technique never been done; in other words the rhythm is uninterrupted.
It seems like a lot of "trap" music is doing this and I don't know what to call it.
A good example is the following mix where it occurs frequently:
1:54:03 (Or 114 minute mark) It's done a number of times after the time posted. I love it, but don't know what to call it.
