The ultimate sacrifice 

When walking into a very ordinary nightclub to find only one very hot looking woman, 9 times out of 10 she will be acompanied by a very dirty looking woman. In order to hook up with the hotter of the two, one of your mates must distract the dirtier one by hooking up with her.

Hooking up with the dirty one is known as making "the ultimate sacrifice".

Furby and Mick walk into the Pavillion, Sydney.
Mick: Look at that stunner over there!
Furby: She is gorgeous.. but look at that ugly mole she is with
Mick: Furby... one of us has to make the ultimate sacrifice...
Furby: .... I want to make the ultimate sacrifice...

needless sacrifice syndrome 

The tendency of action, sci-fi, or fantasy media to needlessly sacrifice main characters for one reason or another.

Charlie from Lost, most characters from Lost, and every tough black sidekick character ever are all examples of needless sacrifice syndrome.

Virgin Sacrifice 

A subtrope of Human Sacrifice, Virgin Sacrifices were generally made in ancient times as payment to a God or some other power, either to keep them functioning or to win their favor in general.

Tribes in Africa and South America engage in ritual Virgin Sacrifice every fall for a good spring harvest/hunting season.

I'm not willing to sacrifice my life for a cupcake. 

Used when someone suggests doing something that is obviously dangerous and stupid.

"You should climb up it and jump off. Just remember to roll when you land."

"No thanks. I'm not willing to sacrifice my life for a cupcake."

Sacrifarce 

What you give up, only to realize not long afterwards that it made zero sense at all to do so!

Getting married a second time was the biggest sacrifarce of my life.
