What it means if a guy teases you with another guy?

If a guy teases you with another guy, it could indicate that he is trying to gauge your reaction or feelings towards both of them. This playful teasing might suggest he’s interested in you and wants to see if you express jealousy or attraction. Alternatively, he could simply be joking around without any serious intentions, using humor to engage with you. It's important to consider the context and his overall behavior to better understand his intentions.
