In my view all of the written above fits to definition of colloquial English. It's type of informal speech that applies idioms, slang etc. The one thing is not recommended in colloquial English is the usage of rude words. But it depends on region where you speak. There are differend idioms and slang in every region.
I believe that our generation is no more flawed than any other generation. According to an article by BBC older generations have always complained about the generation that came after them (http://www.bbc.com/capital/story/20171003-proof-that-people-have-always-complained-about-young-adults) and most of the complaints that our generation faces today are the same complaints that the Baby Boomer generation faced when they were our age. There is something significant about every generation, for the silent generation (63-88) it was the moon landing and assassination of JFK, for the baby boomers (46-65) it was the Vietnam war and Woodstock festival (A festival that introduced a new type of music as well as the "hippie" life style), for generation X (31-46) it was the destruction of the Berlin wall, and for the Millennials (18-30) it is the rise of technological advances as well as the accepting attitude toward different races, cultures, and sexualities. The behavior of our generation I believe shouldn't be seen as "bad" per say, we are all young and just trying to get the most we can out of life, how we are parented shouldnt be used as an excuse for our behavior, just because a person has grown up in a bad house does not mean that they have to carry that with them as they go through life, every person has the ability to define themselves as a person and choose how they want to live and act.
