same as a jackday except over the course of a weekend. Therefore, no human contact of any kind for more than 2 hours in a 48-hour period. Or in the case of long weekends, 2 hours in a 72-hour period or 3 hours in a 96-hour period.
You must have had at least 3 sessions on every jackday of the jackend in order for it to be considered a true jackend.
If you have one session for every 3 hours of the jackend - you have had an EPIC jackend! this does not mean you must have a session every hours, only that if you divide the total number of hours by 3, you should have had at least that many sessions to be considered and EPIC jackend. For example, 48 hours = 16 sessions, 72 hours = 24 sessions, 96 hours = 32 sessions
Dude 1: "dude, didn't see you this weekend, what's up?"
Dude 2: "oh man, i haven't hit anything for a month - my balls were smurfed they were so blue. I had a total EPIC jackend, man."
