The Venus Thigh Trap is experienced when an unsuspecting male is lured by a women into being clinched between her thighs during an intimate (unclothed) or romantic (clothed) encounter. The meaning is a hybrid of the following components:
1. The Roman goddess Venus, who is associated with love, beauty and fertility
2. The Venus Flytrap, the most commonly recognized and cultivated carnivorous plant

Like an insect caught in the Flytrap, if a man finds himself in this position, he may either use what's left of his waning strength to wriggle free, or succumb to the woman in which case she has asserted her dominance.
Man recounting the events of the previous night: "I was making out with Amanda, and one thing led to another. But I really didn't want to sleep with her so I said we should take a break and watch TV. So one moment we were relaxing, and the next thing you know, she had me in a wicked Venus Thigh Trap. After that, I was done for, she had her way with me."
