A slang for 'yes' in Colombian spanish, 'sisas' is used by those who mean to say 'yeah', it is used to make the common 'sí' more casual.

Pretentious wealthy Colombians tend to avoid using this word as they feel it would damage their social status, due to the high stratification of Colombian society.

In an ideal world 'sisas' could be used freely without being judged.
1. Old pretentious aunt: "Only poor people use the word 'sisas'"

Normal person: "Only you and your classist attitude think that"

2. Normal non-pretentious person 1: Wanna go to the movies

Normal non-pretentous person 2: Sisas!

No judgment present
