ASL STEM

Definition

1. to move information across the screen as if the screen were a window or porthole through which you are looking. For example, all word processing programs can scroll vertically, and some can also scroll horizontally. 2. (slang) to type gibberish rapidly and repeatedly in order to disrupt a discussion in a chat room. (This makes all the real messages scroll by too fast for people to read them.)
