How do you reverse-tether your MAC with your Android phone?

Question

Title says it. But, to be clear: My mac laptop has the inet connection and I want to share it with my phone (like, reverse tethering).

I have already enabled share internet connection. But, when I try to pair them with bluetooth, my phone turns on it's internet sharing. As we speak, I am sitting on an airplane desperately trying to get game time on my phone (I should have paired my phone and had it get the paid internet and then done classic tether)
