@ViktorMellgren : While I strongly favor such an alternative, I'm not quite familiar with "Shag" having the same meaning. A quick Google of Shag led to
Wikipedia page on Shag which gave several meanings, none of which match the word it seems you may be trying to avoid. Worse, the Wikipedia page does identify the word as "a British slang term for sexual intercourse", which I doubt the military has prescribed as a daily routine that is required before shaving.
