A phrase typically during road rage--especially when being glared at by snotty female passengers. This phrase can be used in conjunction with hand signals, but is more typically exercised as a way to blow off steam at those road neighbors who just seem to have an issue with the fact that they are sharing the interstate with other individuals instead of owning their own highways.
You nasty woman why don't you just "Pet your dog!" and not glare at me for no reason!

Specifically when a male masturbates or strokes his erect genitalia and would like someone to know it. Used mainly for describing to a significant other over phone calls or public that you are/have masturbating. The reason you would use this term and not just outright say it would be due to things like: They're parents are in the room, you're in a public place, they have you on phone speaker, etc.
"Hey,"
"Hey!"
"Am I on speaker?"
"Yeah, why?"
"Oh I'm just calling to let you know I'm petting my dog.."
"Oh..."
*Takes off speaker*
