'Murder Weapon' (1989) – David DeCoteau.

Perhaps one of the more conspicuously neglected 80s slashers is the feverishly titillating, terminally top-popping, Linnea Quigley produced sledgehammer-savage, sensationally sleazy slasher 'Murder Weapon', wherein two wickedly wholesome B-Movie babes organize a 'coming out of the psycho ward' party, as you do, and this perfectly perky pair of blissfully bikini-clad horror hotties do the nasty with their beer-boozy beaus, and very soon this fearlessly frothy beer bash turns terror-toxic, as it would appear that one especially perfidious party goer has taken the 'party till you drop' maxim to its more luridly logical conclusion! B-movie impresario David DeCoteau's blithely blood-soaked, bra-burstingly bonkers 'Murder Weapon' is a crudely effective, Neon-hued, wide-scream 80s slasher serenade starring the dazzlingly delicious, drop-dead gorgeous horror hottie Linnea Quigley!!!
