noun - a cynical, derogatory, term used to invalidate and belittle someone's acceptance of Christ, after becoming involved with a significant other. Usage requires not actually asking the person in question about their experience, their personal relationship with Jesus, their walk in faith, or any aspect of their testimony. Usually used by those who want to feel intellectually superior to those of faith.

Yeah, I've seen this all before, it's a poontang conversion.
He's saved? I never would have expected that! It must be a poontang conversion.
When someone you have had sex with in the past shows up or are friends with someone you want to have sex with in the future, they are a poontangboomerang.
"Dude! I went to a party with my new girl , and her skank friend showed up that I was down and dirty with the night before! That girl is a poontang boomerang !"
Noun. An insult used to refer to someone who tries too hard in order to compensate for something lacking (i.e. trying to be cool; i.e. Carson Daly). It is often associated with a decreased mental capacity. One of the most vicious insults that can be bestowed upon a fellow human being.
