Hello.
A couple of phrases in Indonesian would be neat.
For a little bit introduction:
Nama saya adalah... (My name is...)
Saya suka... (I like...)
Well, 'saya' is the formal form of 'I'. The semiformal one is 'aku', and the non-formal is 'gue' or 'gua'. So you can replace the 'saya' in the sentences above with 'aku' or 'gue'/'gua'. Almost everyone uses 'gue'/'gua', but honestly I prefer 'aku', it feels more polite and friendly. With the three 'forms' (formal, semiformal, and non-formal), indonesian may sound very complicated, but it is actually very simple if you already know the key.
And here are some everyday phrases
Kurang kerjaan = (adj.) Lack of activity a.k.a nothing to do (usually to comment someone who does unnecessary or weird things; they do it because they have nothing to do)
Jones (Jomblo ngenes) = (adj. or noun) (someone) single but desperately looking for a partner.
Mati saja kau (semiformal)/Mati aja lu (non-formal) = The indonesian form of "Go to hell", but it actually means "You should just die". My people don't want each other to go to hell XD. This phrase is usually used when someone pisses you off, like when someone gets a 100 of 0 in a test while other gets 60s.
Well, I think that would be enough for now :3
