archaeological term used to describe the art of removing dirt from a square hole with a square shovel. If schnitting is done correctly, a large amount of dirt can be removed from a location with unbelievable precision. The material or "schnitt" that is removed can then be sifted using a fine screen. This screen will remove the schnitt from the artifacts - which may include, pot sherds and even coprolite (petrified shit)

A casual invitation / threat used by an individual that is not afraid of fucking someone up.
