What is Splatstick?
1.
Used to describe a motion picture with a suitably healthy dose of humor and gore. Derived from splatter (for blood) and slapstick (for comedy.
If you witness a flick were an arm gets cut off and gives the finger afterwards, or a priest kung fu kicks the heads off a bunch of zombies (as in Dead Alive-) those are prime instances of splatstick at its finest.
