Horse pet 

A pet on the head (human or otherwise) that starts by placing one's hand on the forehead and petting downward over the nose, as if one was petting a horse, but using excessive speed, force and/or pressure. It can be used as a greeting, or as a way to troll one's friends in person.

Horse Pet 

The act of petting someones face as if you were petting a horse's nose. Usually done to annoy the shit out of people.

Last night when i was really drunk at Boar's Head (bar in Athens, GA), I horse petted the shit out of my friends Michael and Angie. Then i horse petted some rando and he looked at me like i was retarded.

Astor's Pet Horse 

Way over-dressed for whatever occasion is at hand.

"Myra looks like Astor's Pet Horse in that hat and high heels at the picnic."

house pet

A significant other who is mostly ornamental. Someone who you are in a superficial relationship with, usually a ditz kept around mostly for sexual gratification.

Her and I aren't exactly discussing philosophy, she's more of a house pet.

Petah. The horse is here. 

A famous line from the hit show Family Guy, delivered by Lois Griffin in the episode (idk lol) while everyone was at the dinner table. The horse walked into the dining room and lois delivered this line.

(a horse walks into the kitchen)
"...Petah. The horse is here."
(petah turns to the horse)
"FUCK YOU"
