Z was at Grandma’s and grandma clapped at a mosquito tormenting or threatening her.
Z saw her “clap” her hands and imitated Grandma, beaming her beatific smile as usual.
Grandma smiled back and said in Singlish: “Zoe beat mosquito?” which is a literal translation from dialect – “pa mung/bung”.
So now when we want Z to clap, we tell her to beat mosquito.
Then she will clap, and beam beatifically.
[Disclaimer: No mosquitoes were harmed by Z’s clapping to “beat mosquito”.
