Soso, sosa, sosilón

[ROBINDESBOIS]

we call sb soso, or sosilón when they are not very animated, they don´t like doing anything. they stay all they at home etc...
Another meaning is sb who speaks very slowly.
How do we translate these two meanings in English?

[AngelicaDeAlquezar]

For the first one, "dull"?

[Glen]

Could I use soso in a wider sense of, for example mediocre, más o menos, apenas aceptable etc.? If so, then finally a word I can say without being accused of speaking spanglish: an exact equivalent of "so-so."
