Oh my, I've been saying cottaging all this time! But in my defence, I'm Canadian, see #7 here:

  British/Canadian term for going to the cottage, chalet or 
  camp located in a rural or semi-rural area.

Thanks for pointing it out. Definitely saved me some embarrassment down the road, like the time I asked the cashier at the grocery store to "bag" me.
