A.k.a. "lingering lovies", this term refers to additional contentedly-cooing cuddlez dat you give someone after da "main hug" has been gleefully administered to her.
One of da best occasions for supplementary snugglez would be if da gal whom you're canoodling wif has a "main squeeze" present at da time from whom she got an initial arms-around, and so your own ear-on-chest nuzzlez come after said "opening-hands-on-back-clasp" by said favorite hunk.
Someone who is very comfortable with physical affection (think Abby Scuito from NCIS) and is not afraid to be bold in initiating it, especially with their significant other.
What happens on lazy days when you don't want to get out of bed. You spoon, then fuck in the spooning position, then fall asleep spooning. Repeat until rejuvenated, someone gets hungry or someone has to pee.
