A national holiday observed on the last Thursday in November. Coincidentally this holiday falls on the same day as Thanksgiving. Celebrated through hours of masturbating before, during, and after the Thanksgiving feast in order to pass time. For some this holiday may last the entirety of the extended weekend.
Another name for Valentines Day; the holiday is similar to thanksgiving in that the few days leading up to turkey day you abstain from over eating so you can make a total glutton of yourself on the one day where nobody looks down upon such an act. On sexual Thanks giving you abstain from intercourse a few days prior so you can have a marathon sex session that rivals Sting's best efforts, may also be used for an anniversary or birthdays.
Husband: You mean sexual thanksgiving, and what do you think we are going to do? You better get ready because I'm going to knock the bottom out of you!!!
Someone who has nowhere to go on Thanksgiving because they are far away from family and friends. A Thanksgiving orphan is someone who is taken in by friends or another family to share in the Thanksgiving feast.
