I used the pejorative term "scrub" in the last post in its proper context
For all your slang needs, rep www.urbandictionary.com. Provides explanations for all the common terms that might slip in the blog, on occasion. Remember, I do use the term "regatta" on occasion.
Scrub is a term from the 1990's referring to a person who don't know the rule of the game, and is restricted by it. We throw it around in MUN (don't be a scrub!), and it's interchangeable with "nuub" for newbie.
