Me: "I'm cumming, I'm cumming, (fart/ pre-eflatulation)... Ewwahh... I'm finished, open a window."

Pre-mature Eclapulation 

Verb or Noun; to clap to early; or a clap that comes too early in a musical or theatrical performance. Either an audience member is too eager to applaud the performer, (either to shoo him off stage or out of sheer adulation) OR the performance is long-winded, experimental, or filled with confusing codas that lead audience members to believe the piece is ending when in fact it has not.

After 4 minutes of silence during piece number 1 in the Tribute to John Cage performance, Kasia believed the composition to be over, causing her pre-mature eclapulation.
