Here one relaxes over many pints! (5,3)
I believe the answer is:
water bed
'here one relaxes over many pints' is the definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
This is the entire clue.
Can you help me to learn more?
(Other definitions for water bed that I've seen before include "Fluid-filled mattress" , "Sleep on it" .)
