Degiri
Degiri means 'push through/out and then cut'.
The term "degiri" is a handy way of describing this short sequence of (the push through, or de) and
(the cut, or kiri).
Bob Myers: The push through and cut often has a vulgar, amateurish feel to it. Among other negatives, Black is reducing his own number of liberties, is settling the shape prematurely by choosing which side to cut on, and the likelihood of aji keshi is high.
However, there are times when this push-and-cut is useful, particularly if black is strong in this area, or along the side.
Bill: I do not get the same feeling. If defending with is almost automatic, then it must be to protect against the degiri, in nearly all cases. How bad or amateurish can the degiri be?
George Caplan Whether such a play is vulgar would depend on the surrounding position. However, it is usually vulgar to push and NOT cut, which I see alot in games, usually played too early and aji keshi. Bob is right, of course, pushing can be wrong, but I believe pushing and not cutting is almost always bad.
