Some lovers, hooting, go too far (9)
I believe the answer is:
overshoot
'go too far' is the definition.
(to overshoot is to go past)
'some lovers hooting' is the wordplay.
'some' says the answer is hidden in the clue (some parts of the word are used).
'OVERSHOOT' is hidden in the letters of 'lovers hooting'.
(Other definitions for overshoot that I've seen before include "Go past unintentionally" , "Go too far" , "Fly beyond" , "Go beyond the mark" , "Taxi too much, perhaps" .)
