Boob has male excited (4-2)

Ross

I believe the answer is:

cock-up

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

'boob' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.

'male excited' is the wordplay.
'male' becomes 'cock' (male chicken).
'excited' becomes 'up'.
'cock'+'up'='COCK-UP'

'has' is the link.

Can you help me to learn more?

(Another definition for cock-up that I've seen is " Something done badly".)

I've seen this clue in The Guardian.
