Snail Mail
The phrase 'Snail Mail' (or 'Smail') refer to mail that was carried by the traditional postal delivery service.
Example of use: Daria –"I didn't get your wedding invitation yet and the wedding is in 3 days." Ruth –"Well, I guess that's why it's called Snail Mail, cause I've mailed the invitations 2 weeks ago and they still haven't arrived, though we live in the same city."
Interesting fact about Snail Mail
The phrase refers to the long time it takes mail to reach its destination from the moment it's sent, as the slow pace of a snail. The first recorded use of the phrase was in a 1942 article posted in the Lowell Sun, however, not until it was common to use Emails to transfer messages and information in the early 1990's, the slowness of conventional mail was so blunt.
