What did Toge Inumaki mean when he said salmon, caviar, roe?

Yes, yes, yes, yes, yes, yes, yes, yes, yes, yes, yes, yes, yes, yes, yes, yes, yes, yes

Ikura (cavier) = Make a reference to someone (except for Toge himself).

Sujiko (roe) = It’s a tough term to grasp because it’s used in so many different contexts. Toge, on the other hand, tends to utter it when he’s taken aback by anything, as in “my, my.”
