I love the word S T A M.
Most people don't even realize that it has a double meaning. It depends how it's used.
The Short and Quick Stam:
The Short and Quick Stam is the one you want people to use on you. This is the I am only joking mate stam. The, oh-so-sarcastic "you look dreadful - stam" stam. The, just-trying-to-be-funny "your cars being towed, mate - stam" stam. It's not a harmful stam. You know when you get dealt a short stam it's just in jest. but then....
Then Long Drawn Out Staaaaaaaaammmmmm:
The long and drawn out staaaaaaammmm is always going to be an insulting one. The person who uses the long staaammm is doing it to be nasty. They use staaaaaammmmm to hide behind their insult, rather than hitting you in the face with it. Its the malicious "your wife's a fat ugly bitch - staaaaaaaammmmm." The sarcastic-mean, "are you pregnant or have you just put on weight - staaaaammmmmm". The below-the-belt "They're towing your car mate - staaaammmmm (now you know they are really towing your car)". The person who uses the long staaaaammmm does so to hide the fact that they are being rude, they use the staaaaammmmm as a cover up, it's the lowest form of sarcasm.
So next time you are stam'd think about how the person used it and then you will know the true intention behind the use of the word.
