When a person or events conspire to create havok with your best laid plans. To ensure a dramatic failure with negative and often dire consequence.
Person 1: I was on my way to lunch yesterday when I got Steve'd!!
Person 2: Oh no, really?
Person 1: Yes way! I got a call on my phone, and not only did my lunch date cancel on me, but the prick made me turn around and come into a last minute meeting
When your best friend is helping his elderly father with chores in the harsh prairie winter and he asks you to keep his lonely farm wife company until he returns and you go over and fuck her.
Your best friend then proceeds to kill himself within the next hours, by going outside and freezing to death when he finds you in bed with his wife.
"Where's Paul?"
"Dead. I totally Steve'd his wife last week."
