liftjacker 

A person who takes control of an elevator (lift) by pressing every button OUTSIDE the lift by running down/up the stairs.

The person watches a crowd go down/up the elevator, the person then runs down/up the stairs and presses the down/up button so that the elevator stops on that floor when no one is waiting to get on. The liftjacker keeps repeating until he/she reaches the top or bottom floor or until he gets caught where he runs out of sight for his next "act of terror".

This causes huge outbursts of anger and annoyance.

lifejacket 

When a chick comes up behind you, clothed or unclothed, and her boobs rest over your shoulders and around your neck resembling an emergency life-vest.

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!

liejacker 

One who "liejacks", i.e. a person that falsely accuses an opponent or potential critic of the very thing that they are saying or doing before they are called out for the very thing that they are saying or doing.

It confuses bystanders about what's true and what isn't to try and help them get away with what they're doing.

See also "liejack" and "liejacking".

She started spreading rumours about her friend and how he fails to satisfy his girlfriend. He comes to her for solace, concerned about what others have been saying about him. She then blames his girlfriend, saying that "she's using you for her own games - you can't trust what comes out of her mouth".

And that is how the liejacker ended their relationship.
