不敢喝雪碧只因我怕透心凉
[bù găn hē xuĕ bì zhĭ yīn wŏ pà tòu xīn liáng]
'I dare not drink Sprite just because I'm afraid to experience a sudden chill', which uses drinking chilled carbonated beverages causing cool sensation down to heart metaphorically to imply that avoiding something potentially bringing too intense emotions or experiences.
