Dropping a Joe Bosco

Joe Bosco
n. A shower fart that blasts soap bubbles like a toxic bubble machine while reeking of poison gas.

Example: “I was caught dropping a Joe Bosco during her shampoo massage—she yelled ‘IT’S LIKE SARIN IN HERE!’ and dove out the shower door butt-naked screaming for air.”

Abosching 

Abosching is when a person is speaking and then breaks into song, particularly in musicals. The term is also used to refer to the point at which the speaking stops and the singing starts.

In West Side Story, the character Riff is talking to the rest of the Jets, when suddenly he Abosches into the song "cool".

In Wicked, Elphaba does some good Abosching.
