Is Indonesian and Malaysian pretty much the same language?

Comparing both is like comparing Italian with Spanish,some words are similar,but they have different meanings and sometimes Indonesians find it quiet funny.For example, awak.In Malaysia awak means "you",but in Indonesia,awak means crew.ANother example,Budak means kids in Malaysia,while in Indonesia, budak means slaves LOL.In Indonesia,Melayu means,getting weaker,as the word melayu is the verb of layu,layu means weak.So melayu means getting weaker.
