Haug Sux a Fatty

This graffiti is carved into one of the walls of one of the bathroom stalls of one of the restrooms on the second floor of the Engineering building, at the University of Saskatchewan:

It has been there for at least six years.  I, personally, cannot recall a time in which it was not there.  Side note: is it still graffiti if it's been carved into something, or is that just straight vandalism?  Anyway, I've been wondering the following since I first noticed this message:

1. Who is/was Haug?
2. Who carved this?  I assume they were male, since this is the men's room.
3. What college(s) were the participants enrolled in?  I can only assume Engineering and/or Agriculture, based on region traffic.
4. What is "fatty"slang for?  Weed?  Dick?  Large women?  Oversized Freezies?
5. "Sux" must mean sucks, right?
6. Is Haug a nickname?  A last name?
7. Does Haug, in fact, sux anything?

I'd like to mention, at this time, that I made a special trip into the stall with my camera in hand, expressly to photograph this commemorative missive - an inscription that will stand the test of time.  I liken Haug to Ozymandias, puzzling scholars of the future.  I would hope that the skilled artisan who carved this spellbinding philosophical treatise also made a special trip into the stall, armed with his tools, enlightenment for the masses on his or her mind, but I am forced to concede that it was probably just some guy, taking a crunch, who recalled that he had his keys with him when inspiration struck.  Perhaps he had to find a way to fill the time, scraping away while his legs went numb.

Stall graffiti puzzles me some.  Who takes a marker with them when they need to grunt one out?  Do you go in with premeditated intent?  Odd.  What really confounds me is urinal graffiti.  Who has the bladder capacity large enough to give you time to write some of these novels?  If you're sticking around post-urine to complete your epic, what happens when someone else walks in?  Do you keep writing?  Do you freeze up like a deer, before bolting for the door?

Mysteries of the universe, these are.
