I believe the answer is:

lollardy

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

'very funny fat boy's latest heretical ideas' is the definition.
I can't judge whether this defines the answer.

'very funny fat boy's latest' is the wordplay.
'very funny' becomes 'lol' (internet acronym for laugh out loud).
'fat' becomes 'lard' (lard is a kind of fat).
'latest' indicates one should take the final letters.
The final letter of 'boy' is 'y'.
'lol'+'lard'+'y'='LOLLARDY'

Can you help me to learn more?

(Another definition for lollardy that I've seen is " Religious movement".)
