Obsessed With Greek Life or A GLO?

OK, let me just start off by saying a LOVE my GLO and the greek system, and do not regret a minute of being in it However, I was watching something and it got me thinking about whether a person can be a little obsessed about their GLO, another GLO or Greek LIfe in general. Examples: a "friend" of mine is in XYZ sorority and she talks about it constantly. Like she lives it, breathes it, and will die it. You remember Spike the dog from Looney Toons and his lil friend who wouldnt shut up and Spike would slap the crap out of him? Thats what we feel like doing to her, even though we wouldnt There was also a sorority on campus that people who were greek and even none greeks were like "girls in XYZ are annoying because they live XYZ, it like they dont have a life outside it." I have also seen people become obsessed with other houses besides their own. Does anyone think a person can be a little TOO(obsessed) into their org or another org? After all there is nothing wrong with having spirit, but what do you think and doesn anyone have any stories?
