Cobhead's definitions
The night before the sesh. (Generally falls on a Thursday/Friday in the UK) The pinnacle of drinking excitement. Everyone waits excitedly to see what father Seshmas will bring them the next day.
“I’ve left some jäger bombs out for father seshmas and a doner kebab for his deer, it is Seshmas eve after all!”
