Dextromethorphan is a salt of the methyl ether dextrorotatory isomer of levorphanol, a narcotic (opioid) analgesic (and DXM itself is an isomer, i.e., a mirror image in the 3D space, of levomethorphan, a substance considered an opioid1). It is chemically named as 3-methoxy-17-methyl-9(alpha), 13(alpha), 14(alpha)-morphinan hydrobromide monohydrate. DXM occurs as white crystals, is sparingly soluble in water, and freely soluble in alcohol. The drug is dextrorotatory in water (at 20 degrees Celsius, Sodium D-line) with a specific rotation of +27.6 degrees.

Dextromethorphan is a codine replacement.
Dextromethorphan can be both the most badass, and most scary drug one could use...NEVER underestimate it!

Taken in the contest of the song Baby's Got Back by Sir-Mix-Alot he is referring to Florence Griffith Joyner a track athlete in the 1988 Olympics who defiantly fits all the other descriptions of what he likes in women mentioned in that song. Not some soda why on earth would you want to keep your women like a soda anyway?
