it stands for Shit Pub Monday, this is where every monday you go to a different local shit pub. set im in portsmouth university by, steven, Alan, Craig, Martyn and Chaz
Its when a person drinks one beer, so they can smell drunk and in turn act drunk. Hence the name S'macktin. It is good when you want to get some but theres only the "ugly girl", you can just be like i was drunk didnt you smell my breath?
