Everyone called him a wacker when he still lived in Liverpool.

That new remix is even wacker than the original.

Wacker operated the compactor with practiced skill to level the uneven gravel.

The Wackers lined up behind the construction site, their engines rumbling as they prepared to compact the gravel.

The wackers swung their mallets in unison to break the frozen ground.

In many factories, the Wacker process is used to oxidize ethylene to acetaldehyde using palladium(II) chloride as the catalyst.
