Making dinner plans with the parents in order to not have to cook yourself.
A tactical dinner operation usually goes like this:
1. Calling the parents wanting to "catch-up".
2. Having the dinner
(3) Bringing any left-overs home, making the operation even more successful, in the sense that you now have food for several days, saving both time and money.
Bro 1: What are you doing on friday?

Bro 1: Smart move, bro!
