他站你身边刺痛我眼线
[tā zhàn nĭ shēn biān cì tòng wŏ yăn xiàn]
The phrase describes a situation of jealousy or emotional pain when the person you care about is standing next to someone else (him), metaphorically saying his presence stings like an eyeliner that hurts my eyes. This implies the speaker’s discomfort when seeing him next to the one they are infatuated with.
