The combination of a cuddle, huggle, and snuggle. They are used toward people affectionately, such as showing love or friendship, sometimes as foreplay. It may seem very similar to just 1 of the 3 combined phrases, but you will realize a schnuggle when it happens due to the added awesomeness and epicness.
Adjective. Derivative of 'Snuggly'. The epic and awesomest word to describe your tender, comfy and fuzzy feeling of epic snuggliness. Not to be used by nubs.
