Napkin of Shame 

When you are in a restaurant and cannot finish what is on your plate. You do no want to look like you are wasting food, so place a napkin over the food left on your plate to try and hide it when the waiter comes to take it away.

"Hey dude, Steve's eyes were way bigger than his belly so now he's had to drop the napkin of shame to try and cover it up"

Napkin Season

The beautiful time of year, typically between 31 March and 10 September in which fine young broads gallivant in public wearing loose-fitting tops; or “napkins”. So named for their free-flowing nature, immaculacy, and the fact that it looks like the funbags are wrapped up in such a serviette; the “napkin” is perhaps the most glorious of all female clothing (far superior to the Jegging).

Screw December, Napkin Season is the most wonderful time of the year!

Nap-kin Sea-son! *clap clap clapclapclap*
