a poo dog is a highland terrier/scottie dog/westie. they just look like little poo's! whenever you see a poo dog, the rule is to blow a huge slobbery raspberry at it, as you would for other stupid rule things like yellow car no returns, and touching red objects after seeing a mail van.
Rach- Whoa! check out that poo dog over there! hahaha
Dan- *winds down car window, and blows a HUGE raspberry* oh how we love poo dogs.
Rach- Totally.

Ottawa Valley slang. When one sticks a frozen hot dog into one's vaginal recesses. It is kind of like a dildo, or a diller. However, it is smaller, and more dangerous due to the fact that a piece could easily fall off and subsequently become cunt junk. Therefore, it should only be used by professionals.
