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.

MSB

Massive Sperm Buildup: suffered by males only; very similar symptoms to a female's PMS.

When a man hasn't been able to bust a nut in a while and thus becomes cranky, bitchy, whiney and down right intolerable.

I wish he would get laid already so he can relieve his MSB because I'm tired of his whiney-ass bitching!

MSB

Stands for Mother Sister Black. A woman that is african-american, has children and is known to a guy as his buddy's sister would classify as an MSB. Most white men have an 'achivement sex list' which includes a mom, a black girl, somebody's sister, a teacher, etc... If a white guy has sex with an MSB it is considered a powerful achievement.

Duder 1: "I can't believe you fucked Garrett's sister. She's half black and has a kid dude. You totally scored an MSB!"

Duder 2: "I know man, it was pretty amazing. Those titties were so nice."

Duder 1: "Damn! You're so far ahead of me now. All you have left on your list is a teacher. I got a lot of catching up to do."
