Judas shuffle 

(Catholicism) The act of leaving Mass early, typically between receiving communion and the concluding rite, without a justifiable reason for doing so. The Judas shuffle is named after Judas Iscariot, who left the Last Supper (the first Mass/Divine Liturgy) early in order to summon the guards to arrest Jesus.

My brother did the Judas shuffle because he wanted to watch the football game.

Judas Shuffle 

"Judas Shuffle" is a knock off of the phrase Cupid Shuffle. Except Judas Shuffle is used in negative reference to a person...

Leaving a lecture or talk before the speaker has completely concluded.

Or

Leaving church near the end of the service or mass but before it has actually ended.

1) Man, as soon as he said, "In conclusion", Half the audience did the Judas Shuffle.

2) Dude, as soon as we started singing the closing song, half the church left.

I know man, Its the Judas Shuffle.
