Warm action

Refers to someone getting more money in their wallet.

Gintoki: Man, it's freezing today, old man

Old Man: It sure is; it might snow soon. They keep talking about global warming, but Earth's only getting warmer on the outside. Here in "Edo," the town and the people's hearts are just getting chillier.

Gintoki: Got that right. When will I get some warm action going on?
