B.Siewert

B.Siewert: Stands for Bitch Siewert.

If you meet a B.Siewert, they're probably an alcoholic or a former alcoholic. Has an annoying high pitch, nasally voice, and is to dumb to know left from right. Usually blonde with long hair too. But most importantly, a bitch.

That B.Siewert thinks she's so cool because she rides motocross.
