jump call 

The ability to just call your buddies up at anytime to say hi, catch-up, watever. First mis-interpreted for drunk call.

Now that I am back in New Zealand, I can't just jump call my buddies anymore, as NZ does not pick up the verizon network :-(

Jump call 

To call someone without prior warning, but scarier. Especially applicable for video calls like teams, zoom, facetime.

Brian from Migration keeps jump calling me about verifying the newest data dump, when I've set my status to busy.
