Lumber Bag 

A term used to describe the scrotum. It is derived from the Latin term that describes the penis as "lumber."

"Bryant just took a shot to the lumber bag while playing street hockey, he may not have kids after that one."

The sticks and stems that remain after cleaning your stash of weed.

Hey, let's grind up the lumberage and sell it to you little bro.

Lumberback

When you have vigorous, testerone fueled sexual Intercourse with an individual wearing nothing but a flannel and a beanie. The tempo if said Intercourse is supposed to match that of the felling of 90 year old oak trees, when an orgasm is reached "timber" is usually groaned out.

I bought my boyfriend a flannel for Christmas and I've been getting lumberbacked ever since.

Five in the front and wood in the back. Not quite a reverse minivan but similar.

I was already in the back door so I loaded her up with a lumberwagon.
