That:
Sounds like a weirdly pronounced way to say que succulènto (succulent)
Which is probs funnier if we knew the meme
and that:
"How succulent", I think. Not sure it's Spanish. Maybe a Spanish in-joke of some kind?
Both are correct. "khe zukulento" is a very and absolutly wrong way to write and pronunce "qué suculento" (How succulent). Personaly, I don't know the meme in question, but for me was hilarious because in the south of Spain (mainly in Andalucía region) people tend to pronounce Spanish in a very particular way that is VERY similar to what is shown here.
So, inevitably, the Spanish community is going to feel more or less tempted to comment, because to us, in one way or another, is a joke too habitual (and hence my comment that possibly only a person who Live in Spain can understood it, of course I didn't know that exist a meme about it ... I'll have to look for it xD).
