Remove the twitter share button

I have repeatedly unchecked the box and saved – it stays. So, instead, I try to change the share words that appear (instead of cool site message, made my own) and my words do not appear. So, back to trying to remove it. It stays and people see it – I cleared my caches – it stays – and others have told me it is there. How to remove the Twitter share button or if not how do I remove this plugin because it is non-responsive to my changes – been trying for hours. (If i deactivate plugin all stays the same – it does not remove these buttons. I like the Facebook share one but not the twitter one since it does not allow me to change the wording.) Please help. Thank you.
