pajero

pajera/o - adj. lazy, literally it describes a person who sits around and masturbates all day, which means they are ultra-lazy. But when I've heard "pajero" used, it means "lazy". Generally people aren't saying they are huge into masturbating, they are saying they are being lazy.

Estoy terrible pajera. No tengo ganas de hacer nada en absoluto.

I'm feeling really lazy. I don't feel like doing anything at all.

A related expression.
Me da paja. - I don't feel like it.
Me dio paja. - I didn't feel like it.

Chilensis, a VULGAR word

This is one of my FAVE chilean words as I identify with it quite a lot. Hehehe.
I'm not pajera all of the time, THANK GOD, but, from time to time, I do come down with cases of pajerez or would it be pajería? Haha. I use this word all of the time.
