stacknapping 

verb - when two (or more) people or animals (or a combination thereof) sleep for a short time in an orderly pile, one atop the other, for maximum photogenicity

Can’t wait to get home and get my stacknapping on with the mister.

This won't take off like planking and owling did. Stacknapping requires more than one foreveralone redditor.

My boyfriend would punch me if I tried to stacknap on him like that.
