banger

I'm a little stuck... Click here to teach me more about this clue!

'firework' is the definition.
(I know that banger is a type of firework)

'bachelor really put out' is the wordplay.
'bachelor really' becomes 'b' (abbreviation e.g. BA=Bachelor of Arts. I am not sure about the 'really' bit.).
'put out' becomes 'anger'.
'b'+'anger'='BANGER'

Can you help me to learn more?

(Other definitions for banger that I've seen before include "Noisy old car or slangy sausage" , "Noisy old car or slang sausage" , "Sausage (Inf)" , "Meaty" , "Old rattling car or slang sausage" .)
