This happens when you are wearing tight jeans while riding through a pasture (or off-road) in a truck. Next thing you know, you got a full on chubby because your jeans are rubbing on your penis. This is caused by the truck rocking back and forth due to the rough terrain.
"Damnit, these jeans are too tight, now I have a pasture chubby."

her: "Babe, why is your penis hard?"

On the ranch, when you don't want the bull in with the cows, you put the bull the field with the geese. "Goose pasture" is that place where the male has no opportunity with sexual relations with the opposite sex. The phrase is aptly applied to the the situation a young husband finds himself in during the last trimester of his wife's pregnancy.
