Unkosher Blumpkin 

The act of a female blowing an uncircumcised male while he is sitting on the toilet and suffering from uncontrollable diarrhea.

Did you hear about Rachel giving the gentile and unkosher blumpkin? I heard it was because of the steam grilled shrimp he had earlier.

Forever unkosher 

To be unclean, dirty, or otherwise undesirable until the end of time.

Steve ate the last hot pocket, he is Forever unkosher.

I saw a homeless man blowing someone for a sandwich yesterday, I am Forever unkosher.
