Buck

Another word for the small of the back. The indentation between the butt and lower back.

Can also be used as a verb: bucking is often carried out in groups of two or more. One person will lay on their front, whilst the partner will lay on their front or side and lay their head on the buck of the first person. If all partied lie on their fronts a chain effect can be created where lots of people can buck simultaneously.
After a session of bucking the bucker and buckee may become clammy on either buck or face.

"He has SUCH a nice buck, it was so comfortable I fell asleep on it"
"We were bucking all night long"
"Everybody needs a buck for a pillow"

buck

The combination of "butt" and "back"; this results when a girl does not have an ass, and so it is not possible to determine where her ass stops and her back starts

"Hey, did you check out Kristy? She's really hot."
"Well, her face is anyway, but she has a buck. She needs some junk in the trunk. Such a waste of a good-looking girl."
