In hockey the slot is the area on the hockey rink directly ahead of the goaltender between the faceoff circles on each side. Those inexperienced with hockey terminology sometimes incorrectly refer to it as the "scoring area".
"Deep slot" refers to the area at the top of the circles, furthest from the goaltender. The distinction of where the deep slot begins is contentious. In general, it is the defenceman's responsibility to guard offensive players in the slot, while the offside winger covers offensive players in the deep slot. Because the deep slot is protected by an offensively minded winger and not a defenceman, forwards will often hover in the deep slot waiting for an opportunity to move towards the net for a scoring opportunity.
