The person you're describing could be referred to as a "tease" or "teasing friend." They might also be considered "playful" or "playfully mocking." If they consistently react in a way that suggests they are influenced by what someone else has said about them, you might also call them "reactive" or "sensitive" to those comments. If you’re looking for a more specific term, it might depend on the context of their interactions and the nature of their relationship.
what do you call a person that if that other person says something specifically about the other person, when that person sees them they will be looking at them weirdly or teasingly

like for ex: eli told Zachacias that he likes nyeria. the next day they all go to an event, and nyeria is standing in line for to get plate of food, meanwhile Zachacias walks past and he looks at her weirdly, and does a "isn't that the girl that Eli likes" face at nyeria
In this context, Zachacias could be described as being "playfully teasing," "smirking," or "giving a knowing look." If Zachacias is specifically aware of the situation (that Eli likes Nyeria) and responds in a way that suggests he's teasing or drawing attention to that fact, you might say he is being "playfully awkward" or "acting mischievously." Additionally, terms like "noticing," "drawing attention," or "calling out" could also apply to his behavior in this scenario.
Overall, you might summarize Zachacias's behavior as being "teasing" or "playful," especially if he is doing so in a lighthearted manner.
