"Gấu" is also a slang for "girlfriend".
The slang word gấu actually means an imaginary boy/girlfriend. The word is the short form of gấu bông (a teddy bear/stuffed animal) which is used by a lonely person as their imaginary boy/girlfriend. ;( However, gấu can also be used to talk about someone's real boy/girlfriend.
How's the pronunciation here? It sounds like bear = rau rather than gua.....is that the correct pronunciation?
Yes, but many Vietnamse pronounce it just like go in English. Lol! True story! Go go go! Allez, allez, allez
If you read IPA, it's [ɣɜ́w]. The first sound doesn't exist in English, it's produced with friction at the position of a "g" sound. It shouldn't sound like "gua".
