rig out
1. To fit, fasten, or equip (with something). Tom just bought a new motorcycle that's been rigged out with a super powerful engine. I'm planning on rigging out my computer with a new processor and some extra memory once I save up a bit of money.
2. To clothe or be dressed, especially in a fancy or fashionable attire. Well, it looks like Jeremy rigged out nicely for the prom. I've got to get home and rig out before our big date tonight.
