slipper dog 

A dog that is so small it looks like a nice and cosy, fluffy slipper.

"Wooh watch out man! That's not your slipper, that's my dog!"

"Sorry man, not my fault you've got a slipper dog"

slippery-do-dog 

When one person sticks a wet finger into the anus of another person.
Usually used to intimidate or to get revenge.
Similar to a wet-willy, but more anal.

Bro #1: Dude, I heard that he just stole your gf!
Bro #2: That's it, I'm going to go give him a slippery-do-dog!

I was asleep. I felt a harsh blow on my dong. I believe I fell victim to a dongslapper.
