'don't do it' is the definition.
I can't judge whether this defines the answer.

'dread hosting ball' is the wordplay.
'dread' becomes 'fear' (synonyms).
'hosting' indicates putting letters inside (inserted letters are welcomed in or hosted).
'ball' becomes 'orb' (both can mean a sphere).
'fear' going around 'orb' is 'FORBEAR'.

'so' is the link.

Can you help me to learn more?
