To unknowingly call someone from your cellular phone, while it is your pocket, purse, or manbag.
"Last night while i was checking out this hot bitch, i accidentally pocket-called my wife and now i have nowhere to live. Can I borrow five bucks?"
When you re-dial the last number called on your cell phone because the send button got pressed in your pants pocket (or purse).
Freind 1: Hey I just got a pocket-call from Jim. He and Mary were talking about how awful your potato salad was this afternoon.
Friend 2: Really? I'm gonna text Jim and tell him his wife dresses like a skank.
