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

'journey in chaos?' is the definition.
'snafu' can be an answer for 'chaos?' (I've seen this before). I am not certain of the 'journey in' bit.

'united supporters making return' is the wordplay.
'united' becomes 'U' (as in Man U, English football team).
'supporters' becomes 'fans' (fan is a kind of supporter).
'making return' says the letters should be written backwards.
'u'+'fans'='ufans'
'ufans' in reverse letter order is 'SNAFU'.

Can you help me to learn more?

(Other definitions for snafu that I've seen before include "Mess table" , "confused activity" , "Chaotic situation" , "mess as usual" , "Bloomer" .)
