Ch-ch-ch-ch-Changes
(Turn and face the strain)
Ch-ch-Changes
Don't tell t hem to grow up and out of it
Ch-ch-ch-ch-Changes
(Turn and face the strain)

Where's your shame
You've left us up to our necks in it
Time may change me
But you can't trace time
An interjection shouted out after a person experiences an excrutiatingly painful burn, or insult. The "Ch-ch" noise refers to the sound of the cocking of a shotgun. The "burn!" replaces the sound of "bang!". That's how painful this particular burn must have been.

Girl: And yet you still wear pants.
Randomfriend: Ch-Ch-BURN!!!
