Step 3: Go to the main proposal section and post your proposal in the correct format.
Step 4: Deal with the trolls and vitriol (much of it may come from me, just a fair warning)

Step 6: Wait until the mods decide to create a poll for your proposal
Step 7: If it passes, congratulations! But don't hold your breath waiting for implementation. If it doesn't pass, congratulations! It probably wouldn't have been implemented anyways.
Step 8: Realize the proposal process is a waste of time and find funny/creative things to propose that entertain you.
