Similar words

かます
かます alone means 'to do something forcefully' or 'to give (a blow, etc.)'. 一発かます is a fixed expression meaning specifically to land a punch or to intimidate.
一いっ発ぱつ
一発 means 'one shot' or 'one blow'. Combined with かます, it emphasizes a single, decisive action.

Etymology

Combination of 一発 (one blow/shot) and かます (to do something forcefully, originally from 'to wedge in' or 'to force'). The expression likely arose from rough, colloquial speech.
