It's tough to get some action when evil is on the prowl. All too often, just as you're getting your mack on, some bad guy shows up to kill one, or both of you. Movies illustrate this scenario perfectly, especially horror movies. Make-out couples are carved up like turkeys in slasher flicks, and the dudes in those movies have to be tired of getting cockblocked time and again. Take a look at these classic examples of movie make-out couple who were cockblocked by evil, and take notes, just incase you're ever attacked by some sort of boogeyman.

Chrissie and Some Guy, "Jaws."

Random McDude and cute blonde Chrissie Watkins are going to enjoy some drunken sex on the beach during the summer on Amity Island. Chrissie swims out, seductively skinny-dipping and beckoning her drunken lover to follow. You think that hanky-panky is coming, but oh no, evil has other plans. The murderous great white shark cockblocks the young man by devouring Chrissie in one of the great opening scenes in movie history.

Bob and Lynda, "Halloween."

Scream Queen P.J. Soles takes her boyfriend upstairs for some sexual excitement. After Bob leaves for some beer (drinking and sex? You are SO dead!), Michael Myers turns him into a shishka-Bob. Lynda is upstairs, waiting for the beer, and for round two of the sexcapades to begin. Unfortunately, Michael decides to rain on her parade by murdering her. Poor kids, cockblocked by an evil guy in a Captain Kirk mask.

Jack and Marcie, "Friday the 13th."

A young Kevin Bacon seeks refuge in a bunkhouse with his lady. They commence to humping, but sadly both are murdered by a shadowy figure before they can re-connect for more sex. Horny teenagers are like rabbits, so it's a safe bet that the pair would have hooked up again before the end of the camping trip. But alas, an arrow through Kevin's throat forever cockblocked him.

Gibb and Trey, "Freddy Vs. Jason."

Two kids with, let's be honest, dumb names. Maybe limiting them to one sexual encounter was enough. Jason shows up to stab the hell out of Trey, who's basking in post-coital bliss, and then fold him up backwards in a collapsible bed. An evil cockblock, sure, but maybe a good one in the Darwinian sense.

Bruce Wayne and Every Love Interest, "Batman" films.

Bruce Wayne gets plenty of ladies, okay? He's a billionaire playboy. But when it comes to the real love, the ladies he really cares about, evil always shows up to cockblock Brucie. They suspend his ladies over bottomless pits, or rig them to explode, or threaten freeze them...we could go on. It's probably better if Bruce sticks to casual sex, because getting really involved with someone is asking for trouble.

Joey and The Nurse, "Nightmare on Elm Street 3."

Okay, so one of the participants in this movie makeout is also the evil cockblocker. Sure, it's a stretch, but it's damn cool. You've never seen a special tongue technique like the one that the evil Freddy nurse displays here. Poor mute Jack is unable to release the sexual tension that may have lead to his ability to speak.
