Me: my girlfriend offered to do a triathlon tonight: me, her, and her twin that I never met before!
Friend: awesome dude, no worries her brother is such a nice guy!

Get the triathlon mug.
A sport where human failures compete.
If you are not good enough at running, cycling or swimming why not just put them together to make a sport for rejects.
Oh you like underaged children, then you mist be a triathlonist right?

My dad left me after coming out as a triathlonist!

Get the Triathlon mug.
Passing a bong, joint and a cigarette between three people and each member smokes all the time. (3 sports like in a triathlon.)
