"Didn't ask"

get really really enthusiastically interested in the watch. ask for details seem super impressed. massage that wealthy ego to the point of basically a blow job. but then just like keep going. see how long you can keep the topic on that one specific watch. don't ever let him talk about anything that the watch means or about the dynamic he tried to establish.

optionally, loose interest and leave without ever having let anything be said that wasn't about the watch. this is how you weaponize autism against egotists.

Sad as fuck that you need expensive set pieces to maintain the facade of your self worth. If I were over here wearing a Timex I'd still be fine with who I was. Would you?

"and yet your dad still don't love you."

"Timex?"

Has this one done it? or how many such watches in do you get to be happy?

Nice.

neat

That's quiet an expensive way to look cheap

Man, it is a shame you can't buy class because you could use some.

"Oh, well this gun costs less than your watch, and yet: hand it over."

"mine was 5 bucks at goodwill, sounds like you got scammed, sorry"

I'd just start laughing and point at them.

good, maybe you can sell it to buy some human decency then

"My wealth is in stocks"

steals his watch

I can afford not to have a watch.

Jokes on you, with the deferred maintenance, my car has negative worth.

I can read digital clocks faster.

What is it for?

"Oh, am I supposed to kiss it?"

Tell him I still banged your mom tho

'I can think of many better uses for the metals in that watch.'

“I don’t mean to victim blame, but I try not to look like I’m worth mugging.”

I wouldn't even hide that watch up my ass.

So you are fiscally irresponsible and you are proud of it? Good to know…

don't. make a "oh poor guy" face and move on. he wants you to engage, to be angry, if you don't he will be mad

"Yes, your fancy jewelry is very pretty. Good job."

Edit: after I stopped laughing, of course.

A lot of replies here still wander into sounding mad imo Instead, I would fake not getting the insult and just make them uncomfortable by saying something like "Wow that's cool :D" and then just move on. Sort of like when you acknowledge a child doing something dumb but they're so proud of it you don't want to ruin it for them.
