tchochki 

Trinket, useless sentimental stuff filling up your book cases and counter space, miscellaneous items collected and set out to enhance your decor, stuff you should probably box up or sell in a garage sale, things kids take when their parents pass away because it reminds them of good times past.

A tchochki could be: Grandma's collection of mini spoons from around the country, mini statues (Lladro), little bowls of stuff for people to look at, figurines, doilies etc.

tchotchkization 

Describes the increase of the presence and display of tchotchkes within any given space, usually referring to an unacceptable or obnoxious level being achieved.

The tchotchkization in this office is getting to be ridiculous- I can't even see the walls!
