Noun - Shanghai Condom- A condom made from Saran Wrap. The penis is wrapped entirely with saran wrap in order to create a make-shift condom for emergency use.
The name came to be while I was dating a girl from Shanghai. We were at her house and I did not have any condoms with me. She said no problem in her cute broken English and ran into the kitchen and brought back Saran wrap. She then proceeded to wrap my penis in Saran wrap and said "See no problem." I used the term for a few years and since have seen it pop up in several conversations.
He ran out of condoms so he got some Saran wrap and made his own Shanghai Condom.
