Randallize

The act of telling someone, like a boss or friend, that you will be arriving at a certain time, only to send a text 2 hours late explaining why you couldn't make it. Thus making yourself look like an ass.

Boss: " When did he say he would be in?"
Employee: " 8:00 am sir."
- 10:30 am
Employee: " Sir, he just texted me saying he had to take his grandma to her funeral."
Boss: " Dammit he Randallized us."
