The act of inadvertently calling someone on a cellular
phone, when your
phone is in your
pocket, or purse, or some other seemingly inconspicuous place where it should not be making calls.
Your
Crazy Ex: Hey, I saw that you called. What's up? Wanna hang out? Wanna get back together? I MISS YOU SO MUCH!!!
You: Eh, sorry for the
confusion, but I didn't mean to call. I must have
butt dialed you.
