1. Shitbox is a colloquialism meaning "anal canal". However, although technically "shitbox" may be used as a direct substitute for "anal canal" it is in fact used almost exclusively when referring to the act of anal sex. Specifically one gets taken up the shitbox or one party takes a second party up the shitbox of the second party. It is worth noting that "Shitbox" is often shortened to shitter".

2. Due to the social unacceptance of anal sex in polite society a secondary derived meaning of shitbox is "very bad".

Unsurprisingly the term is derogatory and used mainly by male virgins in the company of their peers during puberty when discussing their as yet unactualised sexual desires and fantasies.

Especially popular in Kent in the mid 1990's "taken up the shitbox" rose to become the favourite phrase of the sixthform boys of Chatham house boys grammar school in Ramsgate, Kent in the years 1996-8.
1. Nigel have you taken her up the shitbox yet?

2. Yes I bent her over my Astra outside Frank's and gave it to her hard right up her shitbox.

3. And did she like it in the shitbox?

4. What the fuck to you think? Have you ever met a bird who liked it in the shitbox? Oh no you are a virgin aren't you.

5. So are you Nigel you lying shitbox.

6. Shitbox!

A motor vehicle of poor quality, that is valued at or bellow $1000 and is driven on the annual "Shitbox Rally" through extremely remote and isolated areas of the Australian outback. The idea being that each team, of which there are 250, needs to find a Shitbox and prepare it for the Shitbox rally without spending more than $1000 on it.
Teams are also required to raise money for the Cancer Council. Since its inception in 2010, the Shitbox rally has grown to become the single largest fund raising event for the Cancer Council. The rally now raises in excess of $1,000,000 annually for the Cancer Council.
The people that take part in the Shitbox rally often refer to themselves as "Shitboxers".
Teams travel to Australia from all over the world to take part in the Shitbox Rally.
If your Shitbox dies on the rally, it is going in a hole... and your rally is over!
