Backup Call 

Used by people when they go on a first date that they think might be kinda sketchy. A Backup Call is performed by changing a friends name in your phone to someone of high importance (Babysitter, Manager, Son/Daughter, Brother/Sister, etc) and having said friend call you 30-60 minutes into a first date. If the date is going to shit, this can be used to make up an excuse to leave early. Just make sure you have a bullshit story to use so when they ask “what’s wrong?” you have a sentence or two that you can tell them.

You’re welcome, you lying bitch.

Curtis, are you busy Thursday night?
“No, what’s up man?”
I need a backup call at 7pm, do you mind?
“Not at all bro, I’d be happy to”
Thanks man
