look up any word, like pussy:
 
1.
a.k.a Oscar Pistorius someone

1. When you're girlfriend has made plans for the evening, not knowing that you have already made other plans. She tries to convince you to cancel and do what she wants, but you shoot her down (figurative).

2.To shoot your girlfriend with a gun while comfortably seated (literal).
She bought Maroon 5 tickets for the same night i got these tickets for the Lakers game. I had to O_Pisto that!

Fifteen hours in the office and all i wanted was a hot meal. I came home and there was no meal so I reclined on the couch completely famished. I was ticked off I O_Pisto'd her.
