I believe the answer is:

ignoramus

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

'idiot' is the definition.
(I've seen this before)

'topless roman gent? a total flipping' is the wordplay.
I cannot quite understand how this works, but
an anagram of 'roman' is 'noram' which is located in the answer.
'gent?' could be 'gus' and 'gus' is located in the leftover letters.
A single letter 'i' remains which might be clued in a way I don't understand.
This explanation may well be incorrect...

Can you help me to learn more?

(Other definitions for ignoramus that I've seen before include "One is not intelligent" , "Dunce" , "One lacking knowledge" , "Fool" , "Dimwit" .)
