Sexjewgly is simply this - Sex + Jew + Ugly = Sexjewgly.
You see, it originated in the northeast
Philadelphia region where many Jews live. It is used to describe a middle aged, hook nosed, yet unbelieveably sexy Jewish man. Who knows what the attraction is, but only Russian girls and over sexed teenagers use this phrase. You can see it grafitied all over Roosevelt blvd.
A famous example is Tim Roth, who is actually not Jewish, but his name and
nose make
people believe it. Anyway, he is a famous Sexjewgly.
