A marathon bong session where everyone brings their own stash. The last person left conscious wins the bongathon, and as a prize, gets to drink the bong water.
I think I won last night's bongathon, but I don't really remember drinking the bong water.

A long-term endurance bong session. Involving misplaced machismo and one-upmanship much as in a drinking contest.
Although normally used just as a comical way of saying many many bongs were smoked. See mongathon.

2. Want to come over mine hobbit hole for unt bongathon Mavis?
