2.
A term used by students in Ireland. Refers to a week where one goes to college every day for a week, staying in college for the duration of each day, but attends no lectures or other academic activities. Seen by less ambitious students as an achievement greater than that of completing a golden week.
Here lad, you're some waster, you haven't gone to any lectures, you're gonna fail the year.

Eh, i don't think you understand the importance of what im doing, its called a platinum week, dumbass.
