an eternally binding promise (made by two people hooking their pinky thumbs together), which, if broken, will result in the culprit losing his or her pinky
"I pinky swore never to cover my mom's garden gnomes with carcinogens....I did and she cut off my pinky with a cleaver."
a secret between losers; in a desperate act to have some sort of "inside joke" to get thier other friends jealous. didn't work. involves thing such as: jennifer root, dorm daze 2, and jordan.
Pinkyswear is the act of taking the ultimate oath and showing your faith and committment by simply locking pinky's as a gesutre of good faith on a promise...
