It's like saying you're okay with something, even if it's garbage.

'I'm down with this? I'm down with this. It's garbage, but I'm down with this.'

'I'm down with that idea? I'm down with that idea. It's a terrible idea, but I'm down with it.'

'I'm down with this plan? It's the worst plan ever, but I'm down with it.'
