That's not the right use of literally, and at best, is a good use of hyperbole. 20 years is a long time. 20 years ago, SMS wasn't a thing, and IRC and internet chatrooms were more popular. As time goes on, you have things like MSN, Yahoo! Messenger, etc. Emoji were invented after 20 years ago.

Oh, I know what literally means, my friend :-)

But your reply literally made my head explode.

SMS was a thing 20 years ago. Wiki says first SMS message was sent in 1992, and development went far back (beyond IRC).
