the universe's favorite trick: making heat leave the room politely
means The process of becoming or making something less warm, as heat moves away from a body or space toward something cooler.
from From Old English 'col,' the word for cold, which trails back through Germanic roots (a cousin of Dutch 'koel' and German 'kühl') and is related to the same ancient family that gave us 'cold' and 'chill.' The '-ing' ending simply makes a noun or adjective of the act, turning the state of being cool into the ongoing motion of getting there.
