The Wild Women of Wongo (1958)
This is one of those movies where a plot description is best. Prepare for SPOILERS.
Right off the bat, Mother Nature (I hope she was well paid for her cameo) tells us about an experiment she tried by creating two tribes of primitive people; one in which all the men are ugly and all the women beautiful (Wongo), and the other that's just the opposite (Goona). When a Goona man visits the Wongo tribe to enlist their help in fighting the ape men, the women of Wongo notice the difference. The Wongo men notice, and try to kill the Goona warrior, but he escapes unharmed.
Now it turns out that both the Wongo women and the Goona men have rites of passage; the Wongo women have to visit the goddess at the dragon shrine (who expresses herself by magically donning her gator hat and dancing; I am not making this up), and then one of them will be sacrificed to the dragon god (which appears to involve women wrestling gators, though not in either mud or jello). When they are attacked by ape men (who look no more than apes than the men of the Wongo tribe), they defeat them and their bodies are eaten by the gators (by the way, there are several clues here to indicate that this was filmed in Florida).
The death of the ape men having appeased the Dragon god (he prefers ape men to beautiful women; go figure), they return to Wongo to find the men missing, except for one who they find dead. Thinking the men have all been killed by the ape men, they set out for Goona and the good pickings to be had there. The men of Wongo are not dead, though, and when they return to the village, think that the women have been captured by the ape men, and decide also to go to Goona.
Meanwhile, the men of Goona are undergoing their rite of passage, which involves them going out in the jungle without spears and not talking to women, and maybe even doing some skinny-dipping (no gator-wrestling is involved), and then going back to marry one of the ugly Goona women. This makes them easy pickings for the Wongo women, who capture them and take them to the goddess at the shrine, who blesses their marriages. Then the men of Wongo show up with their prospective mates. Can you guess who? I won't give this part away.
Oh, yes, and there's a parrot who gives a running commentary on the action. I've said it before, and I'll say it again; talking birds are not funny.
It has one of the worst soundtracks on record; it even pillages the soundtrack of Plan 9 at one point.
I know. Some of your mouths are watering, while others of you are finding your eyes glazing over. Whichever it is, consider yourself warned.
Watching these things is a dirty job, but somebody's got to do it.
