Strip poker initially rejected by poet (4)
I believe the answer is:
lath
'strip' is the definition.
(lath is a kind of strip)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for lath that I've seen before include "Halt bearing strip of wood" , "Strip of wood, backing for plaster say" , "Narrow strip of wood as used in trellis" , "Thin wood strip supporting plaster" , "Strip of wood used as a base for plastering" .)
