Meeting, something exciting for prisoners? (6)
I believe the answer is:
powwow
'meeting' is the definition.
(I've seen this before)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for powwow that I've seen before include "(Native American) conference or meeting" , "North American native ceremony" , "Informal conference" , "A meeting for discussion, very English" , "Meeting of Native Americans for discussion" .)
