1. verb In animation, to decrease the space between the frames of an animated object to indicate its deceleration. Also referred to as "easing in." Remember to slow in when you animate something coming to a stop. The more frames you include, the smoother the stop will appear.
2. noun An instance of such a technique. Often hyphenated. We squash the character slightly during the slow-in to indicate the force of the sudden stop.
