My mom 86'd me

So I am 13, I go to my mom, "Hey mom, can I have some snacks?" She says, "Sure, but don't overdo it." I say, "I like snacks, so I am gonna go get em." She says, "You're a sweetie, you're so good looking, 86 it." I say, "86 what?" She says, "86 it, just 86 it!" I am so lost, what do I 86? So I come here and you tell me what 86 means! She's always saying it, "86 it," or "86 yourself," or "86 it now," what does it mean? I hope 86 means food, I 86'd a cookie earlier today.<br><br>Edit: all of these replies are so funny, I am crying so hard. <br><br>Edit: I told my mom about this, she burst out laughing. "86 your phone right now." She said. So I came back and said, "86 your 86 responses." She looked at the thread and laughed some more. Thanks for all the laughs you guys!
