'jolly male's fine' is the definition.
'merry' can be an answer for 'jolly' (I've seen this before). I'm unsure of the 'male's fine' bit.

'disembarking from transport' is the wordplay.
'disembarking from' becomes 'mer' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'transport' becomes 'ry' (abbreviation for railway).
'mer'+'ry'='MERRY'

Can you help me to learn more?
