>We label irregardless as “nonstandard” rather than “slang.” When a word is nonstandard it means it is “not conforming in pronunciation, grammatical construction, idiom, or word choice to the usage generally characteristic of educated native speakers of a language.” Irregardless is a long way from winning general acceptance as a standard English word. For that reason, it is best to use regardless instead.

Like I said - I really don't care what you do. I'm just trying to be helpful. Use "irregardless" and people will judge you. If you want to die on that hill, be my guest.
