I'm not sure "ironic" actually has a meaning any more, except in the vague sense of a twist in the course of events.

I've read that somebody put pink flamingos on his yard ironically, because he knew pink flamingos are corny. Okayeee....

The Onion once had a headline: "Young hipsters dine at Applebee's ironically." Applebee's is a mediocre restaurant chain. Okayeee...

If I scrubbed and polished my tile floor to kill dangerous microbes, then slipped and fell on it because it was slippery, that too would be ironic.
