Possible idiomatic reference to the site of Christ's crucifixion in the Bible.
Compare with "... the great city, which spiritually is called Sodom and Egypt, where also our Lord was crucified." (Revelation 11:8), "And they bring him unto the place Golgotha, which is, being interpreted, The place of a skull." (Mark 15:22)
Eunuch: "What's going on over there?"
Leper: "They're leading Jesus all the way out to Bumfuck, Egypt to be crucified, hanged, whatever..."
Eunuch: "Jesus!"
Leper: "What I just say?"
