snugglesting 

The simultaneous act of both snuggling and molesting, usually upon an unsuspecting bed partner.

"Come on sweetie, let's cuddle and go to sleep."
*random groping*
"Stop snugglesting me!"

Snuggulation 

Strangulation by a snuggie.

You fall asleep with your snuggie on and it strangles you in your sleep.

A man died last night due to snuggulation in his sleep.

To suggest a cuddle session, or an equally cozy activity.

See also: snuggestive - to insinuate cuddly or cozy motivations with certain behaviour.

"Then I made a snuggestion, and we put on sweatpants and watched a movie."
"My dog is being so snuggestive curled up on the couch, I think I'll join him."
