If you don't know what an emoji is, just ask Mike Francesa.
On Tuesday, a caller asked the WFAN host if emojis had "something to do with the Twitter."
"It has something to do with Chevrolet," Francesa responded, alluding to Chevy's "Emoji Academy" ad campaign featuring Norm MacDonald.
When that didn't seem to answer the caller's question, Francesa explained that emojis are used in text messaging.
"When someone sends you like a thumbs-up or something like that, you know when someone does that? That's an emoji."
