You're Blue!

It is an inside joke me and my friends made back then. When someone told us that it is alright to join him in his game but his status is "blue" (meaning he is online but not in a game), we often say that phrase stating that he is lying.

you’re my blue means the person is your comfort space, that they make you feel calm just by being there.

It is an inside joke me and my friends made when we played Roblox back in our school days. Whenever one guy said that we are allowed to join the game he is in but that friend's status is still blue (meaning online but not in a game), that phrase is what we used to rant on the one who hosted.
