When you get screwed over by someone you think you know.
e.g. : When your friend asks your girlfriend out on a date behind your back
Alternative e.g. : when a client offers one of your employees a job without asking your permission first
1. I cant believe John just kontominated my girl friend. I am so going to fuck him up when i next see him
2. Jeez, i cant believe that Hugh from XYZ Corporation just kontominated Jill from our sales department. I so want to knee Hugh in the groin but XYZ Corp are big customers of ours!
