Bachelor taking MDMA hip say (4)

Ross

I believe the answer is:

bone

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

'hip say' is the definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.

'bachelor taking mdma' is the wordplay.
'bachelor' becomes 'B' (abbreviation e.g. BA=Bachelor of Arts).
'taking mdma' becomes 'one' (I am not sure about this - if you are sure you should believe this answer much more).
'b'+'one'='BONE'

Can you help me to learn more?

(Other definitions for bone that I've seen before include "Skeletal segment" , "#Close to it is risque" , "Part of skeleton" , "Possibly hammer" , "See 6" .)
