Can be either planned or not, if planned it is a period of time spent inside a liscensed premesis where the sole primary activity is to consume alcohol, most commonly beer. A session can also spontaneuosly occur from a swifty, when the killer phrase "fancy staying for another" is uttered.A session has no set time limits, but is mainly governed by alcohol tolerancy, kung-fu money, opening hours or a combination of the above. A session has no limits to participants, but any more than can fit round one table could be problematic. A solo sesison would only be considered for an alcoholic.Popular sustinence when in a session would be a range of bar snacks, such as crisps, pork scratchlings, or pub grub. When sessioning with freinds, purchasing drinks in rounds is a socially convienient method if not financially. A session is a truly British thing that can only truly be experienced in a british pub since I am yet to experience the warmth and atmosphere in foriegn pubs that would invite you to stay for longer.
Can also be known as a gary player/leo sayer cockney rhyming slang for all dayer
