Paper mail, as opposed to electronic. Sometimes written as the single word
?SnailMail?. One's postal address is, correspondingly, a snail address.
Derives from earlier coinage ?USnail? (from ?U.S. Mail?), for which there
have even been parody posters and stamps made. Also (less commonly) called
P-mail, from ?paper mail? or ?physical mail?. Oppose email.
(Note: Actual garden snails progress at about 10 meters per hour, which is
about 25-50 times slower than the U.K.'s Royal Mail; comparable
measurements for other countries have not yet been made. More biologically
apt terms might be ?sloth-mail? at 250 m/hr or ?tortoise-mail? at 270 m/hr.
