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

'what striped' is the definition.
I can't tell whether this defines the answer.

'tiger say has upset asinine lot' is the wordplay.
'tiger say' becomes 'cat' (tiger is a kind of cat).
'has' means one lot of letters go next to another.
'upset' is an anagram indicator.
'asinine'+'lot'='asininelot'
'asininelot' anagrammed gives 'oninetails'.
'cat'+'oninetails'='CAT-O-NINE-TAILS'

Can you help me to learn more?

(Other definitions for cat-o-nine-tails that I've seen before include "Rope whip made of knotted cords" , "Knotted flogging rope" , "Naval whip" , "Lash" , "Rope whip once used in flogging" .)
