Occurs during the winter when a bear, most commonly of the grizzly or kodiak family, needs to find a nice warm cozy spot to take a several month long nap. What separates this special type of hibernation from the usual kind is that this bear finds a ridiculously floppy va-jay-jay and crawls inside it for the duration of the cold months.
Tom: Hey did you see Patty walk by? It looks like she's put on about 400 pounds in the pelvic region!
Stan: I know, I noticed that as well. Then again, it's almost winter, so I bet that bear we saw in the forest the other day is getting ready for a Scottish Hibernation.
