Verb. Origin is Worcester Polytechnic Institute. The act of failing all one's classes for a term. The term originated because WPI does not record failed classes on students' transcripts. Thus, if you fail all your classes, your report card is clean as new-blown snow. Example: Well, it's no shock that Fred snowflaked; he hasn't gone to class for weeks.
