A sexuality that is very fluid or fluctuates often.
Imagine two perpendicular lines. One of them is a continuum between 100% asexual one one end and 100% hypersexual on the other end. The other line is a continuum between strictly homosexual on one end and strictly heterosexual on the other end. Their sexual preference falls in random spots respective to those two lines, as if you were to dangle a pendulum above them and swing it in a circle.
Some days, Sally feels asexual, but other days she feels hypersexual. Sometimes she likes girls, sometimes she likes boys, sometimes she likes nonbinary people, sometimes she does not prefer either of the two nor anything in between. Sally labels her fluid sexuality as the sexual pendulum.

A potentially painful condition in which a male, often wearing boxers or no underwear, is walking or jogging and the testicles and/or flaccid penis repeatedly slaps against the inner thighs.
Jogger Chad: "Dude... ok, I gotta take a break here..."
Jogger Michael: "Aw, man come on... we got three miles to go."
Jogger Chad: "Dude... fucking got pendulum penis going on right now, k? Gimme a freaking break."
Jogger Michael: "For Christ's sake, you said that two minutes ago."
Jogger Chad: "Fuck off! I thought I had the testies of Papa Smurf last time I tried to tough it out... couldn't beat off for two days."

The periodic movement of the Indian male genitalia before engaging into Kamasutra-type sexual intercourse as part of the corresponding religious ritual.
Indian dude 1: "Why is Mittal standing naked in front of Ansa shaking left and right? Was the curry she made too spicy?"
Indian dude 2: "No, he is just getting ready to make love to Ansa using the kapitza's pendulum method as described in Kamasutra chapter 5."

A sexual position in which the female lays in the jackhammer position and the male enters her from the front with his ass hanging over her face. He will then defecate (note: it must be a log or the metaphor won't work) and let the log swing back and forth before it falls, thus "The Pit and the Pendulum."
That bitch was crazy last night, she wouldn't fuck me till I did The Pit and the Pendulum again.

A sexual act in which an average to poorly endowed bayman with a biblically large scrotum engages in doggy-style sex. The oversized bag swings like a pendulum, crashing against the femaleβs clitoris like the waves of Griquet, causing mild pleasure.
Jeez by, I never had much of a lad, but luckily Jen dies for the pendulum bag.
After gravity has taken it's toll upon the male genitalia a man can now use his scrotum and testicles as a wreaking ball. Assuming he has two, one needs to bounce back into the other testicle sending it hurdling towards the desired object. Thus the pendulum effect.
Bro: How did you get that hole in your bathroom wall?
You: I realized I forgot a towel when I got out of the shower so I was going to helicopter myself dry with my giant schlong but I accidentally pendulum smacked the wall.
Bro: Ouch!
A position taken by someone reacting to a perceived dominant narrative they disagree with that is a complete overreaction and overreach in the opposite direction.
"Pitbulls are actually the sweetest, most harmless dogs ever to exist."
"Bit of a pendulum take, don't you think?"
