The word(s)

I've  been hearing people use the phrase "it's alot".  Generally it is being used to describe overwhelmed with emotion. One of the people I heard use the phrase habitually lies to cover up other lies. When I challenged the lie it caused them to blame someone for something that was an impossible occurrence.  I'm not sure if "it's alot" can be used like "wow" to just say anything to prevent an uncomfortable silence. 

An uncomfortable silence also known as an opportunity to soul to search.
