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.

It’s an acronym standing for Can’t Remember A Fucking Thing. It’s usually used to describe embarrassment at being unable to remember someone (CRAFT moment); going onstage as the lead in the latest theatrical performance and your mind goes completely blank (CRAFT situation); the next morning after a night when you got pissed as a fart and woke up in bed cuddling a traffic cone and a string of fairy lights wound round your prick.
