'jostled' is the definition.
The definition and answer can be both to do with motion as well as being past participle verbs.
Maybe there's an association between them I don't understand?

'tramp on exercise day' is the wordplay.
'tramp' becomes 'bum' (synonyms).
'on' is a charade indicator (letters next to each other).
'exercise' becomes 'pe' (Physical Education).
'day' becomes 'd' (abbreviation for day).
'bum'+'pe'+'d'='BUMPED'

Can you help me to learn more?

(Another definition for bumped that I've seen is " Knocked, ran into".)
