jabronize - To make a friend or coworker look bad so you can look good,

To make a friend or coworker look bad so you can look good, or to get totally wrecked by something dumb.

My friend jabronized me by stealing my lunch and eating it in front of me.

My coworker jabronized me by making me do all the work and getting all the credit.

I got jabronized when my dog ate my homework and I had to write it all over again.
