I use a lot of what are called weasel words because the reality is that they are the most accurate words.  For example, someone buying a lottery ticket will probably lose.  I have trouble saying they definitely will because I know there is a slim chance they will win.  And if 1 in a 100,000,000+ is enough to make me avoid saying definitely, imagine what chances such as 1 in a 1,000 or 1 in a 100 do to my word choice.
