'attempting to deceive' is the definition.
I can't judge whether this defines the answer.

'fbi flung out' is the wordplay.
'out' indicates an anagram (out can mean wrong or inaccurate).
'fbi'+'flung'='fbiflung'
'fbiflung' is an anagram of 'BLUFFING'.

Can you help me to learn more?

(Another definition for bluffing that I've seen is " Attempting to deceive as poker player does".)
