A term used to describe an easy or 'gimme' type of situation. Became prevelant in bars describing girls who were easy to take home, and grew into sports circles. A 'bunny' is a 5 foot jumper, a 20 yard field goal, an open net wrister, or an infield fly ball. Easily made plays.
"We lost the game because Mike missed a bunny at the end. That dude sucks, I ain't playing with him no more..."
