getting up (relatively)early, rushing to the local McDonalds, only to discover you missed the breakfast mark by .0005 of a second.
Guy that got dragged out of bed: Dude, that was such a McLetdown!
Guy that suggested it: sorry, man.

Jeff: Awwwwwwwwwwwwwwwwwww!!!

(noun) an event that may cause one party a source of entertainment due to the frustration of another party specifically-wanting something (food or toy) from McDonalds.
E.g. Keito was pissed off because they no longer served hashbrowns when she arrived at McDonalds about half a second too late! This McLetdown only provided amusement to her sibling who drove her there.

Looking forward to a McDonalds icecream all day only to find when you get there that the icecream machine isn't working/is empty/is being cleaned (although THAT one doesnt happen much) so you miss out.
Customer: Can I have a 50 cent cone please?
McDonalds Chick: Sorry, the machine isn't turned on.
Customer: @#%$! That is such a McLetdown!
McDonalds Chick: Sorry, the machine isn't turned on.
Customer: @#%$! That is such a McLetdown!

Discovering, and worse swallowing, and worse yet wretching up blood and cutting my lip, as a result of foreign objects(sharp plastic) in my and my son's McDonalds sundaes. The first sundaes were watery so we returned them but got new ones with objects inside... I had nuts and my son didn't. I wish I hadn't asked for nuts and I wish I hadn't been served such a McLetdown!
McLetdown - Be glad that the sundae machine was down and you weren't served a sundae like mine because I had a scary McLetdown!

Thinking you won something only to find out that you came in second or lost to someone else. Derived from Kathryn McPhee losing to Taylor Hicks on American Idol.
Kristin: "Who was voted Prom Queen last night?"
Amanda: "Tara, and Nikki totally acted like she would be Queen all year."
Kristin: "Ha. Nikki deserves the McLetdown."
Amanda: "Tara, and Nikki totally acted like she would be Queen all year."
