Acronym, standing for "Done Deal / On The Plane", which is used as an affirmative response to some topic. The term originates from the buzz-phrase lingo surrounding college football recruiting; in many online forums, if a fan or sportswriter strongly believed that a particular recruit was definitely committing to a particular team, they might say that it was a "done deal" and the player was practically already "on the plane" coming to live at his new home.
When Frank asked me if I had bought enough food and drinks for the party, I told him not to worry about it, it was "DD/OTP".
