Acronym for 'Rugged Manly Stubble'. Coined in relation to Viggo Mortensen's portrayal of Aragorn in 'The Lord of the Rings' film trilogy. Denotes the rough, unshaven look typical of 'bad boy' characters in movies and men who simply haven't shaved for a week, as opposed to the carefully cultivated stubble common among movie and sports stars. Similar to, but slightly longer than, sexy stubble.
I looked in the mirror this morning and thought, I've got some great RMS going today!

Man, I wish I could grow RMS like Viggo Mortensen. It looks so rugged. And manly.
