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

'did this?' is the definition.
The definition suggests a singular noun but the answer is not.

'time messing around with adults' is the wordplay.
'messing around with' is an anagram indicator.
'time' mixed up with 'adults' makes 'STIMULATED'.

Can you help me to learn more?

(Other definitions for stimulated that I've seen before include "Aroused" , "Energised" , "Provoked the senses" , "Created excitement" .)
