title: Which is the correct shorthand - "regex" or "regexp"
body: <p>Most of us computer programmers are pretty obsessed about correct terminology. I certainly am, especially because sometimes changing just one character in a word can drastically change its meaning.</p>
  
  <p>So... what is the correct shorthand for "regular expression"? Is it "regex" or "regexp"? On the internet I see both uses, although "regex" seems to be more popular, and the tag list here on SO also includes just "regex". But plenty of people also use "regexp" in their questions.</p>
