'Bunking up' involves multiple (at least 2) people sleeping in the same bed and usually involves spooning in some arrangement (preferably the quad-spoon formation). It generally occurs between the hours of 1 am and 3 am after large quantities of alcohol and a long night of pesting

Sometimes the bunk up follows the age old rule of spooning leads to forking - however - it can be completely platonic.

The ideal number for a 'bunk up' is between 2 and 4 - however there have reports of a 5+ people in a spooning arrangements.

Common issues with 'bunking up' include over heating, a uncomfortable sleep and people getting handsey.
