"Tourist" is one of the fallers (7)

I believe the answer is:

tripper

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

'tourist' is the definition.
(I know that tripper is a type of tourist)

I cannot understand how the remainder of the clue works.

Can you help me to learn more?

(Other definitions for tripper that I've seen before include "at risk of sustaining injury?" , "who might get a booking?" , "person having highly enjoyable experience?" , "Person on an excursion" , "Person on pleasure day out - sounds unstable" .)

I've seen this clue in the Evening Standard.
