Vídeos do TikTok: Is Your Sister Kinda Mean?

A música parece com uma canção de criança, mas não a entendo por conta desta frase "is someone kinda mean" e o que significaria "Thot"... Desde já agradeço

Uma das versões que encontrei:

Is your sister kinda mean
Does she always make you clean
Does she beat you when she's bored
Does she make you do your chores
Does she think she's really hot
But she's really just a thot
Is your sister
Kinda
Mean

Outra versão:

Is your sister kinda mean
does she make you always clean
does she scare away the boys
does she make you do her chores
does she thinks she is hot but she really is a thot
is your sister kinda MEAN.
