Lost on LOST 

The person who has seen every single episode of the hit TV show LOST sometimes can't even describe what is happening on the show to a person who never watches it. This is usually because they do not understand everything that has happened, even though they are experts.

A: "So let me get this right...You've seen all 4 seasons and you can tell me what happening."

B: "Ummmm. No. Sorry."

A: "You are so Lost on LOST."

Lost on the Iditarod 

1- The unfortunate state of being unable to please an especially frigid woman

2- Becoming hopelessly lost after a series of wrong turns in a place where death is more than a little likely

I tried and tried to warm that iceberg, but in the end it was like I was Lost on the Iditarod.

Dude, losing your way in that neighborhood is even more hazardous to your health than getting Lost on the Iditarod.

A word that has simply lost all meaning throughout history. It’s definition has faded into obscurity after being trending on Urban Dictionary for almost two years. 

A sentence in the definition of "Watermelon Sugar" that was colored blue because of the three other words called "A word that has simply lost all meaning throughout history. It’s definition has", "faded into obscurity after being" and "trending on Urban Dictionary for almost two years." which makes the said sentence a link which makes it blue.
