Impromptu remark from awkward lad I bowled (2-3)
I believe the answer is:
ad-lib
But I can't explain it at all! Could you help me understand?
(Other definitions for ad-lib that I've seen before include "without restraint" , "Unprepared remark" , "Extemporise" , "Speak impromptu" , "Spontaneously" .)
