Thrill-seeker very upset with kids (8)
I believe the answer is:
skydiver
'thrill-seeker' is the definition.
I can't judge whether this definition defines the answer.
'very upset with kids' is the wordplay.
'upset with' indicates an anagram.
'very' anagrammed with 'kids' can make 'SKYDIVER'.
Can you help me to learn more?
(Other definitions for skydiver that I've seen before include "I jump out of planes" , "Sporting parachutist" , "one's taken off to get in position" , "Person who performs acrobatics in upper air before opening parachute" , "Acrobatic parachutist" .)
