I heard a seemingly unusual usage of jump in the movie Michael Clayton:
Michael Clayton: I need a loan. I need 80 grand.
Marty: I thought you were done with all that.
Michael: It's not the cards. It's the restaurant.
Michael: I'm sorry to jump you like this. I've been trying to meet you alone for two weeks.
Apparently jump here means to surprise or to trouble the other person on short notice. I can't find this usage in dictionaries. Though I was able to find definitions possibly related to this usage in Merriam Webster:
to act, move, or begin before (something, such as a signal)
- jump the green light
to leave hastily or in violation of contract
- jump town without paying their bills
What does jump mean exactly in the movie?
