A girl with a great body but an unattractive face.

From the redneck phrase, "I only gave her face a 2, but I gave her assinine!"
"So that girl you hooked up with last night, is she hot?"
"Well, sort of... she's an assinine."

Get the assinine mug.
When your canine companion is knotted up nine inches in your rectum.
My wife walked in to catch Fido and I playing a knot so quick game of assinine.
