Does skikkelig actually mean "very"?

I keep getting tripped up here when prompted for the translation of “very.” Seems I always respond with virkelig but Memrise wants skikkelig. When I look up “very” in or, I don’t see skikkelig, and when I look up skikkelig, I don’t see “very” as a translation.

Is skikkelig, meaning “very” specific to a certain dialect?
