To make a chugging or rattling sound, like that of an old engine or machinery; to move with a bouncy or jerky motion while making noise.
Imitative word (onomatopoeia) created to represent the sound of mechanical repetition or chugging. Likely 20th century British/Australian slang derived from the sound 'chud-chud-chud.'
Onomatopoetic words like 'chudder' are proof that language is literally rooted in sound mimicry—our ancestors probably made the same 'chud-chud' noises when imitating mechanical sounds thousands of years ago.
