I’ve been using the phrase “the better part of a ____” recently, it’s an excellent aide for exaggeration, since in most usages you’re just implying that something has been occurring for more than half of a given time period, which can easily be abused.

Example usages:

• I’ve been going to college for the better part of a decade.
• My Dad’s been alive for the better part of a century.
• Dynamic typing is responsible for the better part of the Holocaust.

Do you have any good “Better part of a blank” usages?
