1. n. Professional male of exceptional sexual prowess and appetite in the workplace. Marked by Kenneth Cole pinstripe suits, regular consumption of protein shakes during lunch hour, and the ability to "pull shorties" during happy hours. Typically having three or more romantic interludes per standard work week, the Kiefsultant's fingers will usually have a different scent on his fingers each Monday morning.

2. n. The guy at happy hour with the satin shirt and super shiny shoes who gets the hostess's phone number and then instead of calling her shows up three days later to finger bang her in his BMW behind the Bennigans.
Jack actually had sex with his supervisor and the little Croatian woman who vaccuums the floors in the same week! What a Kiefsultant!
