When an uncircumcised man is receiving oral sex, and his partner becomes startled, causing them to bite down and cleave his foreskin, leaving behind a perfectly circumcised penis and a newly Orthodox Jew.
"Last night was going great until she gave me the Jewish Guillotine and converted me into an Orthodox Jew."
When a male looking to spice up his sexual experience grabs a cold stick of butter and shoves his finger through the center of the stick, then proceeds to finger his woman until the butter melts from friction and sexual heat, granting him a dairy-based lube upon which he uses to dick his woman down.
Man #1: Hey how was the sex last night?
Man #2: I Butterfingered her and it changed her life.
