Ride for a fall? (4)
I believe the answer is:
trip
I believe this is a double definition.
'ride' is the first definition.
(thesaurus)
'a fall?' is the second definition.
(fall is a kind of trip)
'for' is the link.
(Other definitions for trip that I've seen before include "Journey; make a mistake" , "Excursion (while on drugs?)" , "Journey - cause to stumble" , "Hallucinogenic drug experience - lose one's balance" , "day out?" .)
