'cashier' is the definition.
(I've seen this before)

'chap turning on female' is the wordplay.
'chap' becomes 'Sid' (man's name).
'turning' says the letters should be written in reverse.
'on female' becomes 'miss' (miss refers to a young woman. I am not sure about the 'on' bit.).
'sid' reversed gives 'dis'.
'dis'+'miss'='DISMISS'

Can you help me to learn more?

(Other definitions for dismiss that I've seen before include "Remove from office" , "Sack - send away" , "Drop" , "P45" , "Fire - cashier" .)
