Terms of Endearment
Important knowledge I have gained throughout my life:
If somebody greets you by calling you "brader", you can bet your sweet ass that he is not your brother and not even a close friend, more of a fly-by-night acquaintance.
You would probably call your very close friend "a total asshole or a total bastard", but someone whom you really despise and just hate their guts: you'd probably refer to them as "a bit of a bastard, or a bit of an asshole".
Somebody who slaps you on your back when greeting you, probably wants you to cough up something.
Seriously, in the end, if you have 5-10 really good close and dependable friends, that's about right.
Somebody whom can greet you by calling out only a phrase of swear words (e.g. TNMCH, KNNCCB, or just a prolonged nonchalant "tiu....") is probably a very very close friend whom you have had a long history.
... and they say don't use swear words in your blog, its unbecoming ... for me, using swear words appropriately is for emphasis and clarity.
