S///
<chat> s/
foo/
bar/ is an idiom which means "I didn't mean to type 'foo', I meant to type 'bar'".
Its use in
talk systems, especially
irc, comes from the use of s/// as a substitution operator in
Perl,
sed and
ed.
In these languages and tools, s/foo/bar/ would replace any substring matching the
regular expression "foo" with the string "bar".
