American recklessly getting business degree in jargon (4-4)

'american recklessly' is the definition.
I can't tell whether this defines the answer.

'business degree in jargon' is the wordplay.
'business degree' becomes 'mba' (Master of Business Administration degree).
'in' means one lot of letters goes inside another.
'jargon' becomes 'slang' (synonyms).
'mba' inserted inside 'slang' is 'SLAM-BANG'.

'getting' is the link.

Can you help me to learn more?
