martin + osa 

Clothing company owned by American Eagle. They sell clothes in a style stuck somewhere between JCrew, the Gap, Banana Republic, and department store crap. They are marketed to 25 to 35 year-olds (i.e. for those who grew up shopping for A&F and AE and now need to buy clothes to wear to jobs instead of keggers).

Jane: Is that shirt from American Eagle?
John: Hell no, it's from martin + osa. It looks AE, but is double the price!

Eti-Osa 

A conniving, disloyal, manipulative person that is very hairy and has extremely bad breath, body odor, and smells like death down there (if you know what I mean). In her head she thinks she's really beautiful and smart but everyone just makes fun of her behind her back about how much of an idiot she is. She has nothing to her name and just lives off of other people. She acts like she cares and listens to peoples problems only to spread gossip. She thinks that everyone wants to be her friend but in fact, it's just that people don't want to get a whiff of how bad she smells and want her to leave them alone so they act nice in front of her.

Rachel: Did you hear about that girl?
Molly: Stop being an Eti-Osa

Person: OMG! What is that horrible smell? Must be Eti-Osa
