Shelfing

Shelfing is an activity where people try to fit themselves inside a closet. It is a prerequisite for proper shelfing that the closet is not larger than your body volume plus 0,5 m3.

I saw two gals at the museum who had lots of fun shelfing in an antique closet, with the curator planking on the top of it.
