intense

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

'be full on' is the definition.
I can't judge whether this definition defines the answer.

'trendy future' is the wordplay.
'trendy' becomes 'in'.
'future' becomes 'tense' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'in'+'tense'='INTENSE'

'may' acts as a link.

Can you help me to learn more?

(Other definitions for intense that I've seen before include "Extreme - strong" , "Extremely emotional" , "Showing strong feelings or opinions" , "Vived, extreme, acute" , "Strong in degree or emotion" .)

I've seen this clue in The Guardian.
