Thank you for adding me to your friends, totally makes me happy. Nice to meet you! 

I'llrefer you you to Webster's Third Unabridged, in which the definition of lack is "(1) to be wanting or missing."  The first definition of the transitive verb lack is "to be void or destitute of; to be without or deficient in."  And "to stand in need of."  Let's note, too, that the two chief synonyms of lack are listed as "want" and "need."  These are the "core definitions" of lack, and that's why it's a mistake for atheists to keep using that self-insulting definition.

Belief in gods is nothing that atheists lack.  We are not in want of it, and we do not need it.  These are unarguably the primary connotations of the word lack.

Yo, YAA, kindly let me point out, as I had done just above your post jusyt now, that it's a mistake for us to define atheism as a "lack of belief in gods," although it is a commonly advanced definition.  That definition is mistaken because it's the theists' definition of the word.  Many dictionaries offer this definition, I realize, but dictionaries are largely written by theists--theists who fail to recognize their implicit bias. 

The word "lack" carries the connotation of deficiency, the sense that what is lacking is something to be desired. By definition, to lack something is to be in want of whatever one lacks.  Atheists know that belief in god is nothing to be desired.  So we are certainly not in want of it.

The better and more accurate definition is: "the absence of [belief in] gods."

 As George Smith has written:

 "Atheism, therefore, is the absence of theistic belief. One who does not believe in the existence of a god or supernatural being is properly designated as an atheist.  Atheism is sometimes defined as 'the belief that there is no God of any kind,' or the claim that a god cannot exist. While these are categories of atheism, they do not exhaust the meaning of atheism--and are somewhat misleading with respect to the basic nature of atheism. Atheism, in its basic form, is not a belief: it is the absence of belief. An atheist is not primarily a person who believes that a god does not exist, rather he does not believe in the existence of a god."

Wish those on Think Atheist from outside the UK had been there to see the chef guy that day in the photo you commented on! He was hilarious. Thanks for the comment...yeah, he does look a bit KKK - not having them over here, I suppose he might not immediately have thought of the implications...
