Shapnhower: a shag, a nap, and a shower.
Typically done at an SF con between the hours of 4 and 6 pm (prior to dinner) but possibly at other times. Also spelled Shapnhaur, in honor of Dr. Shapnhaur, a visit to whom may be alluded to as an invitation to the above.
e.g. "What have you been up to since the movie?" "Shapnhaur."
...There's something about the term shag that's so brightly forthright it can't quite be embarrassing. I learned the term 'shapnhower' Sunday evening (I have loved some of the dinner table conversations at this year's con) and I've already become quite fond of it.
