Thug's tricycle must stop working (2,2,6)

'stop working' is the definition.
The answer and definition can be both to do with social activities as well as being verbs in their base form.
Perhaps they are linked in a way I don't understand?

'thug's tricycle must' is the wordplay.
I cannot quite see how this works, but
'thug's' could be 'goons' ('goon' can be a synonym of 'thug') and 'goons' is found in the answer.
'tricycle' could be 'trike' (synonyms) and 'trike' is found within the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?
