When you get your dick stuck in another guys foreskin like a Chinese finger trap.
Bro I was pulling so hard and my dick was stuck in the Chinese dick trap. I had to push in to him to get it out.
when you and a buddy use a pocket pussy fucking both ends at the same time, it creates a suction similar to that of a Chinese finger trap, forcing both parties to frot their dicks together inside the toy until they climax.
Tom: Hey did you hear Frank got a pocket pussy on the weekend?
Dan: Yea, me and him are gonna preform an american dick trap with it.
