Parked Like A Cunt.

When someone displays a clear inability to park vehicle in a socially acceptable manner, they are often referred to as PLAC's as they have "parked like a cunt"
Look at that dude over there..... he has the smallest car yet has parked over both spaces, and in a disabled space! Man, that guy's a PLAC!
