A southern term for taking a shit or dropping a duece so to speak. Technically slamming means a massive shit, which in most cases is painful to experience. Due to the fried diet of the south, most slams have large amounts of screaming, moaning, crying, praying, and begging. Many who experience such slams change religions 2 or 3 times and in some cases have even found Waldo during the ordeal. Throughout most of the slam the one taking the slam, also called the slammer, will have slam material better known as reading material to occupy the duration of the painful event. 80% of the time this slam material will consist of up-to-date sports information and news. Though everyone has to live through painful shits it's mostly males who get the brunt of this force. More often than not, males who take slams will have socks on and will keep their phone within an arms reach incase the fire department or medical assistance is needed. It is estimated 1/3 of slammers hallucinate and/or black out due to the amount of pressure put on the rectum and anus.

A term used by postmen (mailmen) in the U.K for mail that is purposely not delivered, usually for top floor flats.
This pratice is not endorsed by the Royal Mail but is common place amongst posties, especially on a Saturday in an effort to secure an early finish.
Slamming involves reintroducing the letter into the mail system the next day back at work.
The undelivered item is refered to as a slammer.
John the postie wants home for 10, he's going to be slamming all the crap for top floors today.
