Eggs on Vijay Amritraj first of all (3)
I believe the answer is:
ova
'eggs' is the definition.
(term for egg cells)
'on vijay amritraj first of all' is the wordplay.
'first of all' indicates taking the first letters.
The first letters of 'on vijay amritraj' is 'OVA'.
(Other definitions for ova that I've seen before include "Prerequisite for procreation" , "Multiple Latin eggs" , "Female egg-cells" , "Female reproductive cells" , "Eggs; sounds like above" .)
