Walk Off Home Run 

A situation where, while having sex, a man elects to pull out and ejaculate on a woman's chest. This event is immediately followed by the man leaving the room having said nothing else to the woman. It is often the case that the man does not even get dressed before leaving. This act is most often associated with one night stands, but has begun making its way into longer term relationships as well. Some believe this act is done to symbolize a male's dominance, while others believe that there is no symbolism involved.

Dude, I'm so bored of just shooting off. Next time I think I'm gonna hit a Walk Off Home Run on her just to change things up a little bit. I think she'll appreciate it.

Dude, remember that girl that we saw last night that looked like Katie Perry? Well, I totally jacked a Walk Off Home Run on her last night! She won't be forgetting me anytime soon.

Walk-Off Home Run 

A term in sports lingo that has gotten completely out of control. Originally coined by Dennis Eckersley in 1993 to describe a home run of such power that you don't even turn around to look ... you just walk off the mound.

The corny fools at ESPN - and their brain dead followers - now use the term to decribe virtually any play that ends the game; walk-off hit, balk, double, single, etc.

"Game-ending" and "Game-winning" have surrendered.

If we use the term "Walk-Off Home Run" why not ... "The Mets lost in the bottom of the 10th on a walk-off groundout."

In baseball, a walk-off home run is a home run that ends the game. It must be a home run that gives the home team the lead in the bottom of the 9th inning or the bottom of any extra inning. It is called a "walk-off" home run because the teams walk off the field immediately afterward. Sportscasters will also use the term "walk-off double" or other such terms if such a hit drives in the winning run to end the game. Although the concept is as old as baseball, the term itself has come into use only in the last several decades.

In the 11th inning last night, he hit a walk-off home run to win the game and the series.

Walk-Off Home Run 

Leaving a fresh dump in the toilet when there is a waiting line to use the facilities at a party, sporting event or gathering. Usually accompanied by exiting the restroom with hands raised and high fives for those waiting in line.

Killer...the line was so damn long for the shitter at that hipster party I didn't have time for an upper decker so I had to go with a walk-off home run
