While trapped in a cave, Grant stayed alive by falling asleep in the security and warmth of his best friend's lifejacket; even though it was a little gay.

the lifehacker effect 

It means having too much traffic on a web site due to its link being posted on lifehacker.com as a feature article, sometimes even causing the featured web site to go down.

I just visited the site, but it seems the lifehacker effect took off again!

Lifehack 

A colloquial term for common sense that makes people feel good about their basic creativity, or lack thereof. Typically lifehacks are not all that helpful, they are simply advertised well so as to provide a false sense of improvement in the user's day to day operation.

liejack 

To falsely accuse an opponent or potential critic of the thing that you are saying or doing before they can call you out on the thing that you are saying or doing. Thus, bystanders and third parties become confused and you stand a better chance of getting away with what you are saying or doing.

Also see "liejacking".

The new girl was quietly different, had a lot of piercings and kept to herself. They didn't like the look of her. One girl one day said "she's blatantly secretly a bully and just hasn't found her victim yet". Thus, they began to yell "bullygirl" at her every day at school. Because of this liejack, everyone else just presumed she was a bully that had been found out and some even started to join in. It only stopped when she finally moved schools.
