I wouldn't call it sarcastic. I would call it being more vulgar or blunt.
You think calling someone "a fat alcoholic Piece of shit" is somehow funny or sarcastic 
I don't get involved in the racial hate or calling women sluts or whores etc....
I am very PG 13 with my jokes. My humor, is how family/friends would rag on each other.
If Coach, Booty, or anyone else doesn't like what I say, then they can let me know, and I will back off.
I'm all about keeping the peace and having a little fun amongst internet friends.
I don't have an issue with anyone here. 
Just look at the difference between how Hurricane Beef attacks Coach, and how I playfully joke with him. It's a night and day difference.
Good post overall. The are some truths therein, which I have firsthand experience with. I take exception to the term blunt though. I believe one can be blunt without being vulgar. Some posts go beyond humorous ribbing into the territory of just being mean spirited and yes, vulgar.
Being an old man, my communication style is likely often off the mark with most of today's folk. I make an effort to not be vulgar or mean. If this makes me something of an enigma on Getbig, so be it. At least I am being true to who I am.
Queue.... your over used video of shutting the door on the old irrelevant man. I'm probably there now. Some of you are not far behind me and all of you will be there before you know it.
