get off my Kool Aid
A saying used when you want to tell someone who's interested in your girlfriend/boyfriend to back off. Using this saying means not only 'back off' but that the target is your property.
Yo, I see you flirting with my man over there. You need to get off my Kool Aid. He's mine so find your own.
Get off my kool-aid
Leave me alone
Get out of my face
Get out of my face
