A portmanteau of "hairy" and "area"; an area on your body that is particularly hairy, but that you would probably prefer to have hairless. Such areas are a matter of personal preference.
I missed that hairea while I was shaving my legs this morning. I'll try harder next time.

Combination of the words "hair" and "areas." The areas in your home where most of the hair balls from your shedding dog seem to collect. These areas can be vacuumed one day and covered with hair again the very next morning.
Wife: Honey, can you vacuum the haireas today before the guests arrive?
