Seanathon 

As it would seem, a "Seanathon" is quite the endurance to be around for long periods, and if that wasn't enough, they eat people for sustenance!

Man, I'm working Yano, doing my regular job, and then this guy named Sean starts. WHAT A SEANATHON they are to work with!

Nothing.

Jeez, he's a real Seanathon to be around.

Isn't your brother's name Sean? Your life must have been a real Seanathon growing up. Surprisingly, you have yet to get eaten.

sextathon 

A sextathon, like a marathon, but with sex, begins usually in the late afternoon and goes into the wee hours of the morning. Just when you think it will end, it doesn't , because one person just keeps going and going. A sextathon can last hours leaving the parties feeling dehydrated and a bit sore.

I am exhausted, didn't get any sleep. I started this sextathon with my BF and he just kept going , and going. Took me a few days to recover.

swearathon 

Letting the swear words rip, swearing like a trooper, swearing when you’re angry to let off steam, swearing with friends for fun, using expletives including the f... word, c... word and s... word. Swearing in a sweararhon can really help some people as it may make them feel better. A sweararhon is best avoided in formal situations such as a job interview or visit to the doctor. Many people like to learn how to swear in different languages.

My mates and I had a swearathon at the pub and we let off some steam.
