As an atheist, what angers you?

[Pat Mustard]

It's become an informal version of "regardless" through bastardization. Sadly it has indeed become an actual word.

I say "sadly" because it annoys me how it makes no sense whatsoever. How can "regardless" and "irregardless" mean the same thing?[...]

How can "flammable" and "inflammable" mean the same thing? "Habitable" and "inhabitable"?  How can "bi-weekly" mean both twice a week and once every two weeks? Why do 'Murricans say "I could care less" to mean "I couldn't care less"? Why can we now apparently say "less people", as well as "fewer people", but we still can't say "fewer milk"?...  

Oh, the joys of a living language...

Oh, don't get me started on the Anglicisation of the Irish language.

Votail my fucking arse.
