<human>: Context:

I like in a house with 4 girls. Our new roommate is from Burma and spends all of her time in her room. We started noticing this faint urine-y smell in the hallways and bathroom, and didn't really pay attention to it. 

Last night, I knocked on her door to invite her to watch a movie with us. When she opened the door, a gust of warm air hit my face and the room REEKED of this smell. I have no idea what it was. It smelled like urine, something nauseatingly sweet, fish, and something sharp (almost like ammonia). The room was acrid. It was not a normal smell. It was way too strong to be body odor or old food left out on plates. 

I was wondering if anyone knew what it was? I casually asked her about a "sweetish smell" coming from her room, and she said that it could be incense that she burned once.

Give me the gist of the text in a nutshell
<bot>: My new Burmese roommate traps herself in her room all day. Her room smells strongly like cat pee, fish, and incense. What could be creating this smell?
