一口盐汽水喷死你别浪费了喷我嘴里
[yī kŏu yán qì shuĭ pēn sĭ nĭ bié làng fèi le pēn wŏ zuĭ lĭ]
An odd yet whimsical expression that translates into 'Spray your salty soda on me instead of you wasting it elsewhere'. Perhaps the holder is suggesting to be the solution rather than waste effort else where in an indirect manner.
