Gutterballs

Gutterballs (2008) is a Canadian slasher you can watch online on iFILM. A midnight disco bowl-a-rama turns into a slaughter when, in the wake of a vicious assault on one of the guests, a masked killer in black bowling gloves starts stalking the lanes. By sunrise the alley is painted red.

Members of two rival teams die off one at a time, and each kill is staged more gleefully than the last. Director Ryan Nicholson came up through the special-effects makeup trade, and it shows: the film leans on heavy, deliberately crude practical gore and pitch-black humor rather than any psychology. It's a pure slab of late-2000s underground grindhouse, made for fans of blood and unapologetic trash. Squeamish viewers should steer well clear; devotees of no-budget extreme horror will eat it up.
