The next step after buying an apartment or house, and moving all your worldly goods, which tend not to amount to much, out of the room you rented with friends/relatives/psychos. This usually involves a trip to Ikea (or similar depending on your geographical location).
Not to be confused with re-furniturising, which is when you move out of the ninth rented apartment or house in eight years with all your manky old hand-me-down gear that doesn't match anything, into your new place, and instantly realise you need to buy a lot of new things to make your house a home.
I went down to ikea and maxed out my credit card furniturising my new gaff.
Isn't it about time you re-furniturised? All your stuff smells of bong water
