Slubbing

Verb - A unique form of affection that can only be truly demonstrated by an entity normally crippled with anxiety (such as 'possums). "Slubbing" is a completely platonic act of attempting to nuzzle beyond what conventional physics would normally allow, given the normal limitations of two distinct objects occupying the same space at the same time. So, the slubber continuously adjusts the snuggle as if in an attempt to find some glitch allowing them to clip through the slubbee as if reality itself were still in alpha test.
