Bit of an urban myth Flyer, I played Rugby for years and never had to endure anything like that........mind you had to drink you own weight in beer....but that's another story.......
I worked at the local uni for many years involved in the sports and it was true from what I saw with my own eyes. Maybe its different in Ireland, anyway everyone has to drink their own weight in beer anyway. I agree with the drinking as I was often invited down to the watering hole where you could tell which team the men or women played for just by looking at them.
Only ever played Rugby in England, however Uni rugby was a tad different from club rugby, what you are describing is student high jinks initiation ceremonies.....club rugby was a little more reserved, besides after a pre-season training session all you wanted to do was throw up, you were too knackered for anything else!

Don't see anything wrong with a good fisting after sweating buckets on the field for a couple of hours!
