I had a boss that would use irregardless ALL of the time. I believe that she thought it made her sound smart. The word "regardless" was the correct word she should have been using.
One thing I have been noticing repeatedly from sports radio gabbers lately - which rubs me the wrong way - is the use of "compete" as a noun.
The Denver Nuggets are showing a high level of compete.
Excessively cutesy-stupid for my taste.
