Sitting in a field, with your mates, getting drunk and stoned. The best place to sesh ever. Nobody else there to care about a group of drunk or stoned youths.
Not recommended in winter. Or in cities. Or in crop fields.
Person #1 "Are you going to the field sesh tomorrow?"
Person #2 "Where is it?"
#1 "That farmer's field on the edge of town, outside the housing estates."
#2 "Of course, where better to get drunk in than an empty field!"
The name of a session in which the chaps gather to binge on carbonated drinks, usually riddled with extraordinary amounts of caffeine. Activities to take place on a calvino sesh may include; pegging it round the local park at 4am, refusing to sleep, aimlessly gaming on almost every single game on the hosts console, eating horrifically cheap and super tasty sugary snacks, etc.
A Rah Sesh - A Rah (Rory) session is when everyone goes to Rory and Mia's house for a jam and drink.Usually the night starts off with the boys inside having having a Jam whilst the girls are outside having a bitch and drink. As the night goes on the trashier we all get. These sessions usually last till early hours of the next day.
