Ignore sexual advance at university (4,2)
I believe the answer is:
pass up
'ignore' is the definition.
(I know that pass up is a more specific form of the action ignore)
'sexual advance at university' is the wordplay.
'sexual advance' becomes 'pass' (passing is a kind of advancing. I am not sure about the 'sexual' bit.).
'at university' becomes 'up' (to 'come up' is to arrive for term, e.g. at Oxford).
'pass'+'up'='PASS UP'
Can you help me to learn more?
(Other definitions for pass up that I've seen before include "Refrain from seizing (an opportunity)" , "Miss" , "Showing neglect" , "Ignore" , "Refrain from taking an opportunity" .)
