Muldoon adventure 

An ill fated trip which with hindsight was a mistake, but no lesson is learned from this mistake. Usually, those who take part must walk many miles to get home, from the ill fated location in which the muldoon occurance occured.

Originates from the misprenunciation of "El Dude", a fraternity in which both members took part in unsucessful adventures.

That party was so lame last night.
I know, just another muldoon adventure.

I have a feeling tonight is gonna be a muldoon adventure.

Saturday was just a muldoon adventure.
