Why mention another girl to see your reaction?

Anonymous
So I have a guy friend that mentioned a random girl just to see how I'd react.. he admitted that he wanted to see my reaction. 2 of my guy friends said he surely likes me based on other signals but why would a guy do that? I don't wanna over think & say he likes me. Also he sent me a meme that says date a 7 and he said: "yes. Or a solid 3 aka me" Was that simply caring or suggestive to date him? And before I said the closest we'd ever be is bffs but he said "you never know" Id really appreciate every response to this question
