trademark

the act of stealing/claiming/
borrowing something from someone else. to make something your own/keep it for yourself.

example 1 - if a girl is trying to hit on another girls man, the girlfriend could say "she's trying to trademark my man!".
Example 2 - if you wanted to borrow your best friends fabulous new jacket, you would say to her "I'm so gonna trademark that jacket"
example 3 - if you wanted to claim the last piece of cake at the table, rather than 'baggsing' it, you would trademark it - as to save it for yourself.
