sneak hug 

The process of sneaking up behind somone or beside them, hugging them and screaming "sneak hug!" as soon as you do it.

Dr. Cox: Nothing ever changes. The Artist Formerly Known as Prince is still just Prince, my ex-wife is still pretty much my wife, 'Grey's Anatomy' always wraps up every episode with some cheesy voiceover that ties together all of the story lines, which incidentally is my least favorite device on television, Newbie continually will try to violate my no touching policy, and Republicans will forever try to raise-
JD: SNEAK HUG! (sneak hugs Dr. Cox)
Dr. Cox: ...Of course, I would go kill him right now, but he actually just helped to prove my point.

Sneakhug 

The act of sneaking up on someone, almost ninja-like, and giving them a hug.
It was first introduced in an episode of the show "Scrubs" when JD hugs Dr.Cox by surprise. The moment he hugs Dr Cox he yells: "Sneakhug!".
To sneakhug, first you have to make sure that the person you are attempting to sneakhug is occupied, like while they are talking,hug them while saying 'Sneakhug!'
Sneakhugs, at the right moment, can be a wonderful experience that can bring joy to an otherwise dull and monotonous day. At the wrong moment however, they can lead to the 'sneakhugger' being slapped in the face or suffering other bodily injuries.

Ash: So yeah, and then I...
