Ultimately swingeing cuts exposed twice — know what I mean? (5,5)
I believe the answer is:
nudge nudge
'know what i mean?' is the definition.
I don't know anything about this answer so I can't tell whether this works.
'ultimately swingeing cuts exposed twice' is the wordplay.
'ultimately' says to take the final letters.
'cuts' means one lot of letters goes inside another (some letters cut their way into other letters).
'exposed' becomes 'nude' (not wearing any clothes).
'twice' indicates the doubling of some letters.
The final letter of 'swingeing' is 'g'.
'g' inserted into 'nude' is 'nudge'.
'nudge' duplicated is 'NUDGE-NUDGE'.
Can you help me to learn more?
(Other definitions for nudge nudge that I've seen before include "but say no more" , "Get prompt on more than one occasion" , "that could have hidden meaning" .)
