Actually it is a contraction of "stream editor". From the manual page
for sed on my system

DESCRIPTION
       Sed is a stream editor. A stream editor is used to perform basic text
       transformations on an input stream (a file or input from a pipeline).
       While in some ways similar to an editor which permits scripted edits
       (such as ed), sed works by making only one pass over the input(s), and
       is consequently more efficient. But it is sed's ability to filter text
       in a pipeline which particularly distinguishes it from other types of
       editors.
