Snipping Arnold 

The insertion of a pair of scissors into a female's anus, then opening the scissors just a pinch, allowing the anus to expand minorly for a short period of time.

"Throw some lube on those scissors for when we decide to perform the snippy-snip-snip tonight"

"Hey, we've been together for 3 months now... can I please give you the snipping arnold?"
