Sales Bastard
Noun A person who exhibits the traits commonly associated with a salesperson such as excessive friendliness, obliviousness to rejection, and a willingness to engage in mechanical tactics like mirroring posture. Often used pejoratively, the connotation is that someone is acting in a manner typical of a salesperson, not necessarily negatively. Term can also be abbreviated as SB.
I feel like such a Sales Bastard - in that meeting I talked about the weather and golf while asking about my prospect's kids then presented a bunch of PowerPoint slides and asked a bunch of arduous questions until it was time to leave. Of course, I complimented the receptionist on my way out. What's that? Did I get the business? You bet your ass I did!
