Rapid bot extremely confused, making for horrible user experience (3,4)

I believe the answer is:

bad trip

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

'for horrible user experience' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.

'rapid bot extremely confused' is the wordplay.
'extremely' suggests removing the centre (only the extremes of the word are used).
'confused' is an anagram indicator.
'bot' with its middle removed is 'bt'.
'rapid'+'bt'='rapidbt'
'rapidbt' is an anagram of 'BAD TRIP'.

'making' is the link.

Can you help me to learn more?

(Another definition for bad trip that I've seen is " problem with horse?".)

I've seen this clue in The Independent.
