A trash can who loves Lindt chocolate and only watches anime like Yuri on ice Haikyuu Tokyo ghoul (more the anime is gay more marta is happy to watch it)
Ex. "do you know marta?"
"Oh yes that girl who always talk about some shits like YURI on ice in the corner of the classroom with her best friend ,ya she is kinda cool"
Marta can be used to describe either a person place or thing that is used for accommodating a person from one Posite to another this could be in a relationship or travel or any other category of life however the other key component of this defining term is that it will cost you more than it is typically considered reasonable for the accommodation from such a thing if it is a Marta model.
Man I wrote that Marta the other day when I was late night in it and s*** man I thought I'd cashed my check last night but I woke up with $2 $2 and then I got a text message that said that my bank account was successfully liquidated by my co-holder but she left an envelope for you..."
You get the idea. Sometimes it's best to just walk alone and save the pennies for your next true love syhe wishing well.
