When someone wants to give you their phone number and you "pretend" to enter it into your phone to call them, but really don't and enter a faux (fake) number
A. "Hey, we should hang out some time. Why don't you take my number and call me"
B. "Sure, what are your digits? I'll ring you some time" But, you don't enter their number, you pretend to and enter a faux number
