Bonking is when you stop the bike, fall on the ground, reach for the cell phone and call your support vehicle aka "spousal unit".

If I find extra time this summer I'm going to be riding at night. Few things are as fun as riding solo on a rural/wooded MUP late at night and seeing things move on the very edge of your headlight beam.
