Cries second after onion flipped? (5)

'cries' is the definition.

'second after onion flipped?' is the wordplay.
'second' becomes 's' (common abbreviation).
'after' means one lot of letters go next to another.
'onion' becomes 'bulb' (onion is a type of bulb).
'flipped?' says the letters should be written in reverse (I've seen 'flipped' mean this).
'bulb' in reverse letter order is 'blub'.
's' put after 'blub' is 'BLUBS'.
