Alah!/ Halah!
Use this to dismiss a clause. The closest equivalence I could think of is 'bulshi*t'. The literal meaning is not as rude but the gesture is.
- Katanya dia bakal dateng / Halah! Ngomong doang! (He said he's going to come / Halah! All talk!)
- Kamu cantik, deh / Alah! (You're beautiful / Alah!)

Amit-amit
It's phrase used to 'deny' bad luck. Pretty much the equivalent of God forbid
- Amit-amit kalo sampai dapat suami seperti dia! (God forbid I'd ever have a man like him as a husband)

Asik!
This is an exclamation that indicates excitement
- Asik! Kita mau ke pantai! (Yay! We're going the beach!)

Astaga!
It's an exclamation that is used to show amazement.
- Astaga! Bagus sekali! (Wow! So beautiful!)
- Astaga?! Kenapa banyak sekali orang? (Oh, dear! Why so many people?)

Bodo
Literally means stupid. It's shows dismissal or no interrest.
- Kok gitu sih? / Bodo! (Why are you like that? / Whatever!)
- Kuambil ya. Bodo amat kalo dia marah (I'll take it, okay. The hell if he's angry)

Deh
You use it to stress a point and put it at the end of a sentence
- Hari ini hujan. Ga jadi pergi, deh (It's raining. Thus we don't go)

Kan
This is to ask for reassurance. Or to stress a point.
- Bagus, kan? (Beautiful, right?)
- Kok beli yang biru? Anaknya kan perempuan! (Why did you buy the blue one? It's a girl!)

Ngomong - ngomong
This is the equivalence of by the way.
- Oh, kamu udah balik? Ngomong-ngomong, kamu bawain pesananku gak? (Oh, you're back already? By the way, did you bring me what I order?)

Nih
Short from ini (this / here).
- Nih, bukumu (Here, your book)
- Serius, nih? (This is serious?)

Oh ya/ Oh iya
You use it when you remember or realize something.
- Tasnya ketinggalan! / Oh iya! (You're forgetting your bag / Oh right!)

Or when you ask or verify if something is true
- Mereka kan pacaran / Oh ya? (They're dating / Really?)

Tuh
Short of 'itu' (that), the opposite of 'nih'
- Mana tuh anak? / Tuh!

Yuk!
This is an imperative term to ask people to do something together, the equivalent of "let's"
- Ke pantai, yuk! / Yuk, ke pantai! (Let's go to the beach!)
