Generally describing very quick visit by band (2,7)

'generally describing' is the definition.
I know nothing about this answer so I cannot tell whether this works.

'quick visit by band' is the wordplay.
'quick visit' becomes 'inout' (I am not sure about this - if you are sure you should believe this answer much more).
'by' says to put letters next to each other.
'band' becomes 'line' (band can mean a strip or line).
'inout'+'line'='IN OUTLINE'

'very' is the link.

Can you help me to learn more?
