This is a little spg sinkie accent. This kind of tone will have a sudden increase in pitch and the pitch will last for a short few sentence before is put backed to normal pitch .
It is indeed nauseating that once I saw a sinkie horse punting lao uncle gan them deep deep inside a fully packed public bus in a lao hokkien tone.
The uncle mentioned something about them trying to imitate amdl (Knnbccb gong way mai gong hosay and angmoh lanjiao etc) but the thing is they were with one amdk. The aftermath was kind of embarrassing+shocking+doesn't know what to react for everyone, including myself as I was standing next to them.
I could only see the little spg zipped immediately and whispered to the amdk about What the ganning was about.
Amdk have a wtf reaction but all of them dare not look at the uncle lol.
