The act of shaving one's head after admitting the futility of attempting a combover or similar baldness-concealing measure.
I'm sure glad Steve decided to cave and shave. That combover was getting ridiculous!

Get the cave and shave mug.
The act of shaving when your not supposed to. Times such as No Shave November or on any bet that involves going for a long period of time without shaving.
Random Dude- Hey are you doing No Shave November?

Other Dude- Hell yeah man
