Nothing to do with the post, but I find onomatopoeic words funny. I doubt if your eyes can actually make a sound like woot woot if you make them big while surprising, but I guess, it would be the right sound for that. Nice found from bahasa gaul (slang) Indonesia.
Aku mau bertanya – I want to ask..
Oh, aku sudah lupa – Oh, I already forgot
Woot woot, lupa kenapa? – (surprised – could be O_O), forgot why?
