It's hard to imagine what else he meant. The assumption is that he got interrupted mid-typing and accidentally sent it.

I think it was "coverage" but he fell asleep tweeting, it posted and then he slept without realising what had happened.

I frequently fall asleep while browsing on my phone and wake up having clicked ads, articles I had no interest in, silly contextual links, etc.

This is even better if you imagine it as him passing out and dropping the phone on his face, bouncing off his nose to get the 'fefe' and landing on his cheek to press send.
