bantathon 

A prolonged session of banter. That is having amusing, sometimes nonsensical, chat with friends or just generally having fun. The word is derived by combining banter with marathon (since a marathon is a 26 mile long race and thus
takes a long time to complete).

1.'What work did you do in class today?'
'We didn't do any work at all. We just sat around chatting. It was a total bantathon!'

2.'Are you going over to Paul's tonight?'
'Yeh of course, it'll be a bantathon.'

bongathon 

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.

When neighborhood dogs who are outdoors in their little adjacent yards all begin to bark in unison in response to something unknown to the human mind.

Yup, it’s another two AM barkathon; they really are all part of one enormous pack, despite those fences!
