I'll call you yesterday

A sarcastic phrase used to signify that you actually won't call or interact with someone in the future. The phrase implies that you would have theoretically called them "yesterday" if you really cared. This phrase is primarily used a means of blowing someone off.

Jim: So did you meet up with that girl you got coffee with last week?

Nick: Nah, she blew me off and never texted back after. It was an "I'll call you yesterday" type of situation.
