Sesh. Sesh is devouring through several grams of cocaine. Deciding that the pills you bought off your mate the other week would be a fab idea to then chuck down your throat. Also realizing later that the guy your with has MDMA to smash and then washing that down with the goodness of a vodka or two. Oh wait? Someone's offering MCAT? You're definitely not going to say no to that are you before realizing the time is 9:43 am and you've been at it 13 hours in someones grungy dungeon of a living room. THAT is sesh.
"We so need to sesh tonight" "No he's definitely not down for the sesh. Boring." "Literally has the dirtiest sesh last night, I didn't leave until 9:43am"

Where a group of two or more people play call of duty for a ridiculous amount of time - usually into the early hours of the morning. This involves a shitload of banter!!

Sesh comes from the word session.
Cod is short for call of duty and is a fuckin intense fps!!
'Sesh it up boiiis'
'Sesh on cod mate'
'Big sesh tonight lads'
'Sesh from 6 til 6 yeah?'
