A type of sesh where those involved know it will not be infact Casual.
Two
people minimum will be assumed missing; One group member will be in a far away land by the next
morning giving you paranoia that they might have told you of their plan of "casting a ring into the fires from where it was created"; or something like that, while another will disappear for two days and reappear unharmed leaving you questioning magic and your faith in everything you read in the Harry Potter books between 1997 and 2007.
The non-drinker of the group becomes the biggest party
animal always with a pint in each hand but also the biggest problem when they blackout cause of their size or it's
time to be sent home in a taxi
Local councils will be questioning the disappearance of many traffic cones in the area of which will appear in someone bedroom the next
morning.
The sesh initiator always appears to have his shit together until the comfort of his own home where anything that can hold liquid becomes a
toilet to urinate in; regardless, it becomes a
bi weekly group ritual.
