Verb. and Noun.
The situation when, after coitus, two people, in that case one male and one female, lay still on their sides (also called spooning), in which the penis of the male person remains inside the female person's vagina, until it
ultimately becomes flask and inert. When the two people fall asleep under the effect of
post-coitus endorphin, that's where the term takes all its sense. Do not mistake with the similar term
Sleeping Bag.
