Con escaped bottom first (6)
I believe the answer is:
delude
'con' 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 there's an association between them I don't understand?
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for delude that I've seen before include "Cause to believe something untrue, deceive" , "Cause to believe a lie" , "Deceive, lead on" , "Mislead, beguile" , "swindle" .)
