This comic is referencing this meme, which in turns is referencing this clip from an Indonesian telenovela.

The context of that clip is that the woman is bullying and forcing her workers to plant seeds in her garden using nothing but a spoon and a fork. The source of hilarity comes from how, taken out-of-context, the woman seems like a profound idiot who earnestly called what's clearly a spoon a hoe.

Reine herself was so amused about the meme partly because she mistakenly thought it was her own voice and she was like, "I don't even remember ever saying this!"
