A term used mostly by gay men to depict something unpleasant, foul, or undesirable. Often replaces words such as stupid, dumb, gay, etc. Ugh, this is so vaginal, I have to work a 9 hour shift today! Those pants are straight up vaginal.
Warning signs such as fear and/or nervousness around other dogs, displays of aggression only under certain circumstances (while on leash, in the presence of food, in the presence of the owner, etc.), or most commonly, over-the-top play behavior can be seen at any stage of the dog's development.
In some cases, the development of a neurological problem through illness or injury can affect the dog's judgment and behavior. Hydrocephalus, head trauma, encephalitis, epilepsy and brain tumors can all cause aggression and strange behavior in dogs. Hydrocephalus is the most common of these conditions to cause sudden aggressive behavior.
