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".
