Backbiting (gheebah) means mentioning something about a person (in his absence), that he hates (to have mentioned), whether it is about: His body, his religious characteristics, his worldly affairs, his self, his physical appearance, his character, his wealth, his child, his father, his wife, his manner of walking, his smile, it is the same whether you mention that about him with words, through writings, or whether you point or indicate him by gesturing with your eyes, hand or head.
As for the body, is when you make fun of how someone looks, or mentioning any bad quality in him, as saying: "he is blind", "he limps", "he is bleary-eyed", "he is bald", "he is short", "he is tall", "he is black", "he is yellow", "he's too thin", "he's too fat". As for his religious qualities, it is when you say: "he is a sinner", "he is a thief", "he is a betrayer", "he is an oppressor", "he doesn't pray", "he prays so fast", "he does not behave well towards his parents", "he does not pay the Zakat duly"." As for the worldly matters, then it is when you say: "he has poor manners", "he does not think that anyone has a right over him", "he talks too much" …etc
Allah says in the Qur'an:
"O you who believe! Avoid much suspicion, in deeds some suspicions are sins. And spy not neither backbite one another. Would one of you like to eat the flesh of his dead brother? You would hate it (so hate backbiting). And fear Allah, verily, Allah is The One Who accepts repentance, Most Merciful" (Qur'an 49: 12)
AND
Abu Huraira reported Allah's Messenger (may peace be upon him) as saying:
Do you know what is backbiting? They (the Companions) said: Allah and His Messenger know best. Thereupon he (the Holy Prophet) said: Backbiting implies your talking about your brother in a manner which he does not like. It was said to him: What is your opinion about this that if I actually find (that failing) in my brother which I made a mention of? He said: If (that failing) is actually found (in him) what you assert, you in fact have backbitten him, and if that is not in him it is a slander. [Sahih Muslim Book 32, #6265]
So actually nothing on this thread was really backbiting...
