The act of taking a shower with interchanging water temperature; going from very hot to very cold, rapidly. This can be repeated numerous times.

Typically done from hot to cold in attempts to wake up or "refresh" ones self, the action can also be reversed (cold to hot) prior to bed.
"Wanna get dinner?"
