An external Engineer who pretends to have all god given code-writing-abilities to built "the next big thing" but in all actuality doesn't qualify and once given the deal secretly hires a real but less expensive Engineer to do the job.
Hiring Person: "Great, before you receive the deal I'd like you to quickly show me your code-writing-skills, just a precaution to be sure you are not an pretendgineer" Pretendgineer: "Well, actually I ain't really prepared to write right now BUT if you want I can send you a codesample by next week? "
A developer that rocks the code hard, while looking good, dressing well and being adored by colleagues and fans alike.
