jacker

Raises heavy loads

A jacker is someone who jacks—steals, hijacks, or takes by force.

The term appears most often in compounds: a carjacker steals vehicles, a hijacker commandeers planes or ships.

In internet slang, a thread jacker derails online discussions.

The word carries an aggressive edge, suggesting someone who seizes what isn't theirs: Some jacker grabbed my bike right off the porch.
