The Flying D

When you use your fully erect penis to hit someone, i.e. your friend or lover, in the face. You must run across the room adjacent of the target, yelling their name; at the mid way point of the room, to gain their attention, then aiming for the nose of said person after jumping in the air, bringing your erect penis down like a drop kick.
If done correctly, their nose should be bleeding.

"Frank... I hate you..."
"Why?"
"Because I think you broke my nose when you gave me the Flying D."

D-mail

To send someone an email where the only thing associated with the email is an attachment of a dick pick. Essentially the dick version of being Rick Rolled.

"Paul sent me the nastiest D-mail today! He said the attachment was of a the biggest thing imaginable, but it was just a picture of his dick!"
