Helmeting 

Like the similar definition on this page, the act involves inserting one's head into the particular orifice. The original example that I've seen, and most others have also seen, is a video of a bald man putting his head (up to his ears) into a woman's vagina.

Did you see that video where that guy put his head in that chick's pussy? That's gotta be one seriously loose hole for helmeting.

helmeting 

A sexual practice, most likely between two men, in which the goal is for the one to insert his actual head into the anus of the other. This is accomplished by the receiver having his spincter muscle severed by a knife, so his ass cheeks more or less flap apart. The giver then lubes up his shaven head and goes to town. It is uncertain whether this practice is supposed to be (more) pleasurable for the giver, or the receiver.

Raoul had to go to the doctor's to have his butt cheeks sewn back together after he was finished helmeting.

Dog Helmeting

Act of doping a dog up with muscle relaxants and laxatives, putting it on top of your shaved head, pulling down on the hind legs, and stretching out its rectum to fit on your head like a hat.

Dog Helmeting: Known among aficionados as Dög Hëlmüting

Step 1. Shave your head. If the dog is long haired, shave the dog's posterior and rectum area as well;

Step 2. Feed dog laxatives and/or muscle relaxants disguised as doggie "treats" so that the dog rectum will expand and dialate wider;

Step 3. Lube now shaven head (if laxatives were used in the previous step, excess feces may be used as well);

Step 4. Place dog on top of head, rectum covering top of head. Careful for the head may become submerged in the rectal cavity causing suffocation;

Step 5. Spin dog.
