'''Teen-age Strangler''' is a 1964 horror picture set and filmed in the city of Huntington, West Virginia. There's a mysterious killer targeting young(ish) women by strangling them, leaving their bodies in the open and marking their foreheads with lipstick.
Said killer has also appropriated one of the club jackets from a local drag-racing gang, leading to the protagonist Jimmy being framed for the murders at first. Eventually, suspicion drifts to other members of the gang, until the real killer is found.
The movie is punctuated with a musical number in the middle named "Yipe Stripes."

!!''Teen-Age Strangler'' contains examples of the following tropes:
* AdultsAreUseless[=/=]ParentalAbandonment: The few parents seen in the film are probably among the worst examples you could find. Jimmy's father seems far more concerned with how Jimmy's criminal record affects the ''parents' social life'' than how it would affect the boy's future; meanwhile, Betty's mom is overly excited to meet a police officer, and her dad is definitely the "hands-off" type.
-->'''Dad:''' That's your job [to protect the children], isn't it? That's what you get paid for!\\
'''Det. Anderson:''' And what's your job as a ''parent''?
* ChekhovsGunman: [[spoiler: The janitor.]]
* ChewingTheScenery: The female protagonist's mother and Mikey are some of the most notable examples of what happens when "community theater goes to the silver screen."
** Also, Jimmy and Mikey's angry dad, who manages to say "by Jupiter" with a straight face.
* DarkReprise: The murderer's theme is a DarkerAndEdgier variation of "Yipe Stripes".
* DullSurprise: A cop tells a woman that her neighbor has been murdered. Her "[[CreepyMonotone Oh, no!]]" is about as flat and lifeless as you possibly can get for ''any'' sort of response, let alone hearing ''your neighbor has been violently murdered''.
-->'''Crow''': (in the most flat and lifeless voice possible) It wasn't ''me'' who was murdered was it?
* TheFool: Non-comedic example in Mikey, though he was probably intended to be more a [[LittlestCancerPatient Littlest Autism Patient]].
* InspectorJavert: Anderson
* JerkJock: Curly
** HeelFaceTurn: After [[spoiler:being accused of multiple murders]] and [[spoiler:narrowly surviving a nasty auto accident]], Curly becomes a much kinder and gentler guy.
* LargeHam: Mikey, especially his "He didn't steal no bike either!" moment. He's not even the only one in the cast overdoing it.
** HamToHamCombat: He was only following the example of the gal who played Betty, as she was the only one in this film who had any kind of previous acting experience.
* NonIndicativeName: There is no teenaged strangler, nor does the strangler kill teenagers exclusively. Likely intentional, not just to cash in on the "Teenage X" genre, but as a RedHerring (Would you look at anyone other than [[spoiler:the janitor]] if you weren't looking specifically for a teenager?)
* RecklessGunUsage: The detective just ''fires'' through a school window in the general direction of Betty and [[spoiler: the janitor]].
* StickyFingers: Mikey is a kleptomaniac. It becomes a PlotPoint.
-->'''Betty''' ''(as "Yipe Stripes" plays on a jukebox)'': Gee, that's a nice song.
* ThereAreNoTherapists: [[JustifiedTrope That's okay, though,]] as apparently there's no such thing as grief or psychological trauma, either. Tony's girlfriend is killed, and he just goes to school the next day no problem. Betty is nearly murdered and her attacker is shot dead in front of her, but give her 24 hours and she'll be back at the malt shop shakin' her groove thang to possibly the worst song ever recorded.
