For some reason, i have this terrible mid-80's slasher flick stuck in my head but cannot remember its name.

A guy is out trying to stop his homicidally insane twin brother to clear his own name.

at one point, said insane brother cuts someone in half at the waist with ...no, not a chainsaw but A HEDGE TRIMMER... the chainsaw's longer, thinner cousin and after doing so, pauses to wipe his finger in the blood that is splattered all over his shirt and taste it, proclaiming "Nope, that's not cranberry juice"

perhaps by naming it, i can cure my fixation with it.
