When there's simply too much mustache to handle. If you can't handle the 'stache then get out of Missouri; the mustache capital.
The other week I was chilling in Missouri and I kissed my girlfriend and she complained about my mustache being sufficiently prickly. She claimed it was mustache madness! She was then escorted out of the state because she couldn't handle it.
