Past tense of "liejack".
Someone that falsely accuses an opponent or potential critic of the very
shady thing that they're doing before they are called out for that
shady thing by that opponent or potential critic.
Bystanders and third parties become confused about what is and what isn't
reality, giving the liejacker a better chance of getting away with their liejacking.
The horrible man wondered what it would be like to throw a party in his neighbour's house. When his neighbour left for the weekend, leaving a house-sitter in
charge of the house, the horrible man paid the house-sitter a visit, got chatting and got him blind
drunk. He then threw a huge party at the house, trashing the place.
In the morning, after everyone left, the horrible man phoned the
police and liejacked that the house-sitter had thrown a wild party and trashed the house whilst the neighbour had been away.
The poor house-sitter, having no memory of the
night before, was arrested and lost a friend.
