a term used for a nonexistent condom, derived from the fact that Jesus was a virgin and therefore would not have needed a condom at all. it makes sense, trust me.
so, basically, sex without a condom.
Yeah, me and Janet hit it off with a jesus condom last night.
Having unprotected sex with your girlfriend or wife and praying to Jesus that you didn't get her pregnant.
What!? You can't be pregnant again, I was wearing a Jesus Condom.
