look up any word, like blumpkin:
 
1.
The act of laying together naked and fucking, while taking little breaks throughout to snuggle and then resume fucking at some point. The penis can remain inserted during the snuggle portion of the fucksnuggle. Fucksnuggle, fucksnuggler, fucksnuggles is also a sweet nickname.
"Baby, I love you so much I don't only just want to fuck you, I want to fucksnuggle the shit out of you!!"

" I figured we could spend the day together, sleep in late, do a little fucksnuggling and then go have brunch."
