What bothers me tons is when people assign the word "friendship" to any kind of relationship in which the two parties involved have met each other in person less than 3 months before and have made mostly shallow interaction. That's not significant enough to assign the word "friendship". Most likely, you're a "glorified contact", nothing more. This is what I'd like to call the "cheapening" of friendship, where affection is given away wholesale without regard to depth and understanding.
Another big violation in my eyes is the constant focus on the word "love". It means what? I hate saying it, but it's thrown around much more than the pigskin in 5 NFL seasons. If you say you "love" someone in a context outside of jest, unless it's some dear family member or someone with whom you've grown together in a relationship of respect and meaning (be it a significant other or a real friend), it's frankly insulting to the intelligence.
I'm not anti-love or anti-friendship for that matter, I'm simply pro-sincerity.
