Take trousers off and return to bed at some stage (5)

I believe the answer is:

debag

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

'take trousers off' is the definition.
(I've seen this before)

'return to bed at some stage' is the wordplay.
'return' is a reversal indicator.
'at some stage' becomes 'ag' (I can't explain this - if you can you should believe this answer much more).
'bed' backwards is 'deb'.
'deb'+'ag'='DEBAG'

'and' acts as a link.

Can you help me to learn more?

(Other definitions for debag that I've seen before include "Remove (a person's) trousers" , "Strip of cords maybe" , "take trousers off" , "As a prank remove pants" , "Deprive of trousers" .)
