A lack of time behind player's call? (2-5)
I believe the answer is:
no-trump
'player's call?' is the definition.
'no-trump' can be an answer for 'call?' (type of call in the card game bridge). I'm not certain of the 'player's' bit.
'a lack of time behind' is the wordplay.
'a lack of' becomes 'no' (lack of money is no money).
'time' becomes 't' (abbreviation).
'behind' becomes 'rump' (informal term for the buttocks).
'no'+'t'+'rump'='NO-TRUMP'
Can you help me to learn more?
(Other definitions for no-trump that I've seen before include "possible contract" , "Bid in contract bridge" , "Highest bid in bridge" , "Bid type that's top" , "The kind of contract" .)
