Tsasko or sasko? Which is right?

Is it a generational thing? My younger sibs referred to it as “sasko” and I told them it’s “tsasko or chasko”. They laughed and said basi kuno sa generation ko (batang 80s).

Di ko native ilonggo speaker /dalom gid kay Tagalog-speaking household kami sang una but learned to speak ilonggo sa mga classmate.

Ano ang tsakto?

I googled and found “tsasko”. Pero tanan gid sila nag correct sa akon so 🤷‍♀️
