Hello Kiba22, It is "atrasado (a) " and could mean 'behind' as Mihriban mentioned and also 'short of ' something or to be in arrears when it comes to payments. It means also 'underdeveloped, slow, backward'. In some contexts it means 'ill'. Examples : - atrasado de noticias = behind the times - estar atrasado en pagas = to be behind in payments, to be in arrears - un número atrasado -> a back number (revista) - un astrado mental = a mentally retarded person.

Atrasadilla. Atrasada (-illa is a diminutive form in Spanish) It means Be behind, arrive late.

used like as you say "atrasadilla" means that the girl (lets say) is silly, short of wits. sure, "atrasar" is a verb which contains the meanings stated here. The use of this diminutive makes the one saying it not feeling unpolite but keeps intacte the rudeness of the statement. It connotes quite vulgar user and low socioeconomic status.

Atrasadilla is the diminutive from Atrasada as says Mihriban. Normally it mean to be behing someone or if you had a lot of hungry and are you eating in this moment you can say "La tenia atrasada",it mean you had hungry time ago. I hope it help you.

ah bueno :) gracias!
