西瓜西瓜甜死你妈
[xī guā xī guā tián sĭ nĭ mā]
"Watermelon watermelon sweet enough to make your mom faint with joy." While humorous, the meaning might seem strange or harsh to foreigners because this phrase mixes exaggeration with an impolite way of speaking in a lighthearted manner that might not easily translate across cultures.
