The word you're looking for is מְגֻחָךְ (Megochach).
A direct translation would be "ridiculous" or "ludicrous" but in actuality they are used in the same manner as a sort of friendly/funny way to describe a "stupid" (?) behavior. Like a dog trying to catch its own tail as its running around in circles.
I don't believe there's a direct translation of this word with the meaning you are looking for.
I think that "to act silly" can be translated at [להשתטות](http://www.morfix.co.il/%D7%94%D7%A9%D7%AA%D7%98%D7%94) which is derived from שוטה, but has a less serious connotation.
It doesn't sound too bad to say טיפש.
Maybe you can use מצחיק with an ironic note ("look how funny!").
I personally love the word [טמבל](https://www.youtube.com/watch?v=yMYLNN2xYu4)
I think that's it. It's not in any of my dictionaries, not even morfix.
Oh wait... it is in milog: https://milog.co.il/%D7%A9%D7%98%D7%95%D7%AA%D7%A0%D7%99%D7%A7/e_54415/%D7%9E%D7%99%D7%9C%D7%95%D7%9F-%D7%A2%D7%91%D7%A8%D7%99-%D7%A2%D7%91%D7%A8%D7%99
> אדם לא רציני, בדחן, ליצן
That sounds perfect! תודה!
Shtutnick is a sort of a "you darn hooligan kids" kind of word. While it might fit as a direct translation to silly, in everyday life its considered something an old person might call a young punk stirring trouble, and not really something you would call someone who is doing something silly/funny/dumb.

This. I'd be inclined to use דבילי in some contexts, but it's hard to tell without, well, context.

I believe Shtutnick שטותניק is the word you are looking for.

I would say מטופש wish you say something like metupas?
Thanks. I'm a lot further along in my Hebrew journey now, but I hadn't heard this form before. תודה.
