S-MAIL 

S-mail is like e-mail, but there is no body, and the entire message is conveyed using only the subject line.

Usually practiced using mobile devices (Blackbery, etc)

drop your tail here's your mail

When one person places mail inside the rectal cavity of their partner immediately after engaging in an act of sex.

angry sex forced sex forced entry insertions chain letter

while engaged in doggy style sex, the *angry "rear" partner pulls out and quickly forces ANY piece of mail (regular mail, advertisements, boxed package) into the anal cavity of the front partner while saying "Drop your tail here's your mail"!!

Under ordinary circumstances the immediate, uncontrollable, unconditioned reflex is to drop tail.

*NOTE: the majority of the time the ""rear" partner has just received a piece of mail officially addressed to the "front" partner. The mail is always addressed from a secret lover.

If you never get it, just be thankful.

Check's in the mail 

When you have no intention of paying for something/don't believe something. People used to pay for things by check and it would take some time to arrive. If you didn't have money, you could buy something without paying, saying "the check's in the mail."

"Hey, when are you going to pay me for that weed?" "The check's in the mail, bro."
"The supreme court is going to uphold the voting rights act? Yeah right. The check's in the mail."
