Chunk saved by crone served up for tramp (7)

I believe the answer is:

galumph

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

'tramp' is the definition.
The definition and answer can be both to do with motion as well as being verbs in their base form.
Perhaps they are linked in a way I don't understand?

'chunk saved by crone served up' is the wordplay.
'chunk' becomes 'lump' (synonyms).
'saved by' indicates putting letters inside (I've seen this in other clues).
'crone' becomes 'hag' (synonyms).
'served up' is a reversal indicator (in a down clue, going upwards).
'hag' back-to-front is 'gah'.
'lump' going into 'gah' is 'GALUMPH'.

'for' is the link.

Can you help me to learn more?

(Other definitions for galumph that I've seen before include "move inelegantly" , "Stride exultantly" , "Move clumsily, ponderously (colloq.)" , "Bound so excitedly" , "proceed awkwardly" .)
