A moron, a dumbass, someone who is oblivious to the fact that there mere presence makes others want to vomit.

A sly way to insult someone without them knowing it.

Someone who thinks they are cool but just ends up making a fool of themselves.
"Bubba is such a JackFace!"

"What's up Jackface!"

"Look at that guy trying to pick up my grandma, what a JackFace!"
