2.
Men without balls who will answer yes to any query from their boss/superior regardless of the question's intelligence, bearing, or appropriateness. It is usually intended to farther the yes man's carreer by getting and staying on the boss's good side, but may have the opposite effect.

Yes men often ruin the productivity or usefulness in the department they work in, as they are unwilling to provide any form of original idea, opinion or more importantly criticism to their boss and thus contribute to disconnect between managers and workers.
I can't stand yes men, they get ahead but do nothing actually important!

A yes man is a person who agrees to every opportunity they come across, no matter how crazy it may seem and they do not weigh the consequences.

Yes man(no spoilers) is also a movie that was produced in 2008 starring Jim Carrey. In this movie he makes a conevant with himself to agree to any opportunity that he may come across.

Some people believe they are living life this way by opening up every possible gate to a better future.

Urban dictionary editors who accept any definition that comes along. It is not known why people do this but theories include:
i) they are attempting to get 100% acceptance stats to look 'kool'
ii) they do not like hurting peoples feelings by saying 'no'
iii) they are dumb

plural: yesmen
