sales weasel 

A dishonest, slimey, skanky, sales WHORE who will do, say, and promise anything to separate you from your hard-earned money.

That frickin' sales weasel sold me one of those totally uncessary long-term warranty packages when I bought my Hugo.

sales weasel 

A derogatory term for a member of sales staff in a typically corporate environment. This term is often employed by technical staff and customer service, who must support the products that the sales weasels have sold, typically without knowing what the heck they're pushing on the customer.

That slimy sales weasel sold this customer something they didn't need and doesn't work, and now they're chewing my ear off!
