Answer by taking a quote from the following article:

Jacqueline DeLois Moore (born January 6, 1964) is an American professional wrestler and professional wrestling manager. She is best known for her time in WWE (back-then Federation/Entertainment) from 1998 to 2004, as well as working for World Championship Wrestling in 1997-98 and later Total Nonstop Action Wrestling as a wrestler, manager and road agent. She began her career in World Class Championship Wrestling, but was well known in the United States Wrestling Association, where she was a fourteen-time USWA Women's Champion. She later moved to World Championship Wrestling, where she briefly managed the team Harlem Heat.

Moore and Mero separated on the November 22 episode of Sunday Night Heat, and the jilted Moore formed a new alliance of women known as the Pretty Mean Sisters (PMS) with Terri Runnels, who was separated from her husband, Goldust. During a match between Mero and Goldust on the November 23 episode of Raw, Jacqueline and Terri entered the ring and low-blowed both men.  They originally formed an alliance with D'Lo Brown and Mark Henry, accompanying them to the ring for a match against Val Venis and The Godfather in December at Rock Bottom: In Your House. In January, Terri claimed to have suffered a miscarriage after she was knocked off of the ring apron by Brown. The guilty Brown became a servant to PMS, who forced him to wrestle his friend, Mark Henry. The deception lasted until February 1, when the ringside doctor told Brown that Terri had not been pregnant. PMS then feuded with Brown by costing him matches and attacking his new manager, Ivory. Jacqueline returned to the women's division in March, and on the April 12 episode of Raw, she, Ivory, Tori, and Sable took part in a four-way match for the Women's Championship. The match was declared a no-contest after Sable's bodyguard Nicole Bass stormed the ring and chokeslammed the three challengers.  In May, however, the women had switched their allegiance to a wrestler named Meat. That same month, the stable expanded once more to incorporate Ryan Shamrock, who had been spurned by the womanizing Val Venis. As part of the storyline, the three women used Meat for his body as a "love slave", forcing him to have sex with them and wear wrestling tights that resembled a pair of tight underwear. After Shamrock left the WWF, Terri and Jacqueline continued to assist Meat in his matches. However, tension began to grow between the two women as Terri, in storyline, exhausted Meat with hours of sex before his matches and then berated her fatigued lover when he lacked the energy to win matches and Moore finally end the alliance by July.
