a man is said
to have laid a beaver trap when he 'lures' a woman
into having sex with him (repeatedly) with the promise of marrying her soon. After his hunger is satisfied
enough, the man backs off from his commitment.
(this especially happens in conservative
societies of developing countries where
girls consider it a taboo to have sex before
laying a beaver trap is the only option for the sexually-starved & commitment-phobic guys. In such coutries, a man accused
of laying a beaver trap is booked under the charges of rape)
Ajay: Hey Vijay, I can't believe it. How did you manage
to nail that conservative gal ?
Vijay: Ya man, it wasn't an easy task. Finally, I had to lay a beaver trap.
