MSB
Maiden of Surpassing Beauty:

She is among the fairest maidens in the land, rarely seen in life and more commonly the denizen of fairy tales and the fervent dreams of youth. Her visage inspires feelings more acute and much less vulgar than lust, although both are likely to be experienced by the hapless onlooker. Whilst she may be dressed in plain attire during a sighting, you will always remember her, upon reflection, as if bedecked in regal garb and adorned with jewels. Her countenance is arresting. The heart is stricken after an encounter with this rare creature.
Dude, I passed MSB in the hall yesterday. I couldn't even look her in the eye, it was too powerful.
