Gag-a-thon 

The act of performing fellacio to the point of gagging, not once, not twice, but repeatedly. The gagging won't stop you from sucking his cock.

"My girl was on a gag-a-thon last night!"

"Dude, right on!"
"Word. I kept thinking she'd stop but that gagging didn't stop her from going down."
"Awwwww shit."

Gagathon 

The Gagathon is a contact sport founded in the early 1900s. The sport was founded by Sir Gargatrude Gargancious Bedworth. He sadly passed away due to a lack of strawberry jam in his system before his semi final clash against Phil Basham Bashingle Bedworth. The sport has taken off since 2008 as Phil Basham Bashingle Bedworth took over as president of the sport, since then hundreds of people have competed and watched this truly amazing sport. The Gagathon is a tournament where 2 players strip down and the winner is decided by a player entering there bollocks into the opponents arse. The players before a match have to consume 2 litres of strawberry jam so that the no deaths occur.

I’m going to the Gagathon next week lad, you coming?
