Revealing mistake: A sign's wooden support gets shot at the beginning, but you can see where the pre-prepared weak point is in the support before it gets "shot."

The Texas Chainsaw Massacre 2 (1986)
Plot summary
Directed by: Tobe Hooper
Starring: Dennis Hopper, Bill Moseley, Caroline Williams, Jim Siedow
Young DJ Vantia Block is hosting a music show when two renegade hoodlums phone her and start making trouble. The situation changes rapidly as the kids drive to a passageway and get sawed to pieces by Leatherface while the shocked DJ listens the kids' screams. Local sheriff approaches Block and convinces her to play the recording made from the phone call on radio, hoping that the killers would show up.
Drayton: The small bussinessman... always, always, always gets it in the ass.
Trivia: Bill Moseley got the role of Chop-Top because he made a parody short film of the original "The Texas Chainsaw Massacre". Moseley's film was called "The Texas Chainsaw Manicure". Series co-creator Tobe Hooper saw the short and loved it so much that he cast Moseley in a major part when "The Texas Chainsaw Massacre 2" went into production.





Answer: It's basically Leatherface's version of an orgasm. Stretch appeals to his sexuality in order to survive, and he's aroused. He uses his chainsaw as a phallic object, rubbing it against her leg and then pressing it into her groin, and is panting, which obviously symbolizes his idea of sex. And then he becomes aggressive, revs up his chainsaw, and destroys the studio in an explosive emotional display, not unlike the strong physical/emotional sensation that comes with an orgasm. You could also theoretically make an argument that the mess he creates by sawing and throwing things around specifically represents male ejaculation, which involves a pulsating release of semen and can be, let's just say, "messy" sometimes depending on what sexual activity you're doing.
